Ask Me Anything about photo manipulation
And by “me” I mean “someone far smarter & more seasoned in this discipline.”
Dr. Hany Farid “has been called the ‘father’ of digital image forensics by NOVA” & has partnered several times with Adobe. More recently he formed an imaging startup with my old boss, longtime Photoshop VP Kevin Connor. This Thursday at 4pm Eastern time he’ll participate in a Reddit Ask Me Anything event.
[Update: Here's the transcript of the session. Hany's quite a witty dude.]
Incidentally, Kevin tells me that “At one point there were people coming to the Fourandsix site after searching for ‘Abraham Lincoln porn.’” And with that, these guys just won the internet.

Some rather brilliant imaging tech from Microsoft
The company’s Photosynth technology has been public since 2006, and while it’s been cool (placing photos into 3D space), I haven’t seen it gain traction in its original form or as a free panorama maker. That could now change.
The new version stitches photos into smooth fly-throughs. Per TechCrunch:
[U]sers upload a set of photos to Microsoft’s cloud service then the technology begins to looking for points (“features”) in the successive photos that appear to the be same object. It then determines where each photo was taken from, where in 3D space each of these objects were, and how the camera was oriented. Next, it generates the 3D shapes on a per-photo basis. And finally, the technology calculates a smooth path – like a Steadicam – through the locations for each photo, and then slices the images into multi-resolution pyramids for efficiency.
Check this out:
Once you’ve clicked it, try hitting “C” to reveal & interact with the 3D camera path. Here’s an example from photographer David Brashears, who captured Mt. Everest during one of the highest-elevation helicopter flights ever attempted:
So, will we see this become more common? It’s the first presentation I’ve seen that makes me want to don a wearable, lifelogging camera on vacation.

Content-Aware Fill as… animation?
Invisibility cloak, engage!
From the project site:
Since Photoshop introduced the content aware fill tool, it has been familiar between several artists who used it to create different concepts. All what I had seen till now are pieces working through static images, but Zach Nader made in 2012 optional features shown, a 02:10 min video using the same tool over some commercial cars in which the texts, cars and people have been replaced by the content aware’s background. I find very interesting the glitchy movement over a constant and quiet background.

Sneak Peek: Playing with Lighting in Photoshop and After Effects
Sylvain Paris (creator of previous eye-popping tech demos) presents a sneak peek of a way to transfer the appearance of lighting in one image or video to another. Any yes, you’ll find Rainn Wilson’s interjections annoying. I recommend skipping the first 1:30. (Can anyone tell me exactly how to do that with embedded YouTube content, by the way?)

Sneak Peek: Perspective Warp in Photoshop
If I may echo Rainn Wilson, “Oh my God, that’s ridiculous.”
Note: This is a technology demo, not a feature that’s quite ready to go in Photoshop CC. With the move to subscriptions, however, Photoshop and other teams are moving away from “big bang” releases & towards more continuous deployment of improvements.
[Update: I know that a number of people aren't digging Wilson's schtick. Hats off to Sarah for being such a pro under pressure.]

In memoriam: Petro Vlahos
I can’t claim to have known his name, but like you I know his work: Petro Vlahos pioneered blue- and green-screen techniques & founded Ultimatte before passing away this past week at the age of 96. The BBC writes,
Mr Vlahos’s breakthrough was to create a complicated laboratory process which involved separating the blue, green and red parts of each frame before combining them back together in a certain order.
He racked up more than 35 movie-related patents and numerous Academy commendations.
By coincidence, I came across the following peek behind the scenes of The Hobbit. It bears out what Robin Shenfield from compositing firm The Mill says of Mr. Vlahos’s work: “It’s the absolute building block of all the visual effects that you see in television and movies.”

Augmented-reality app translates newspapers for kids
Color me deeply skeptical, but intrigued: The BBC reports on an app that modifies the paper version of The Tokyo Shimbun in ways kids might appreciate:
“What it’s really about is something that’s been talked about for a long time, about content being presented in different ways depending on who the user is,” he said.
“It means two versions of the content – a grown-up one and the kids one. That has enormous potential. It also tackles a big gap in young readership.
This makes me oddly wistful: I’m Proust-ing out, almost smelling the newsprint & listening to the “funny papers” rattle as my dad read me cartoons, or as he’d read news & obits with a drink after work. The real obit, of course, is for the paper newspaper: I’m afraid all this will show up as a quaintly hilarious discovery that flits by on some future adult’s in-optic-nerve newsfeed. But whatever; I’m suddenly, and surprisingly, all choked up.

Why Adobe publishes research
Adobe publishes some of its best work (e.g. tech behind Content-Aware Fill) in the academic community, rather than keeping it a trade secret, as some other big software companies do. Dan Goldman, one of the brains behind CAF, writes,
First, by encouraging publication, we make it attractive for the best minds in the business to come work in our labs – we count several former and current University professors among our ranks. Second, our researchers draw on the wealth of knowledge in the academic community as well – a great deal of our research is done in collaboration with graduate students like Connelly. And third, the rigorous demands of peer review keep us motivated to try truly new things – rather than being content to simply do all the old things better.
Check out the rest of Dan’s post for more insights into how the groundbreaking Content-Aware Fill came to be.

Lytro cameras add “perspective shift”
Remember that Wayne’s World “Camera one, camera two!” scene where he opens & closes one eye at a time? (No, you probably weren’t born when that came out; but I digress.) Lytro’s “perspective shift” feature works a bit like that, letting you switch among two subtly different points of view on the same scene:
It’s cool, though my big hope here remains that such technology offers a better way to select elements in a photo by detecting their varying depths. [Via]

New Adobe tech to help video editors
It’s far from the flashiest task, but placing cuts & transitions in interview footage can be crucial to telling a story. Adobe’s Wil Li plus UC Berkeley-based collaborators Maneesh Agrawala and Floraine Berthouzoz have unveiled “a one-click method for seamlessly removing ’ums’ and repeated words, as well as inserting natural-looking pauses to emphasize semantic content.”:
To help place cuts in interview video, our interface links a text transcript of the video to the corresponding locations in the raw footage. It also visualizes the suitability of cut locations… Editors can directly highlight segments of text, check if the endpoints are suitable cut locations and if so, simply delete the text to make the edit. For each cut our system generates visible (e.g. jump-cut, fade, etc.) and seamless, hidden transitions.
Here’s more info about the project.

A new Photoshop extension detects image manipulation
I’m excited to announce that the company founded by my old boss & friend Kevin Connor, working together with image authenticity pioneer Dr. Hany Farid, has released their first product, FourMatch—an extension for Photoshop CS5/CS6 that “instantly distinguishes unmodified digital camera files from those that may have been edited.” From the press release:
FourMatch… appears as a floating panel that automatically and instantly provides an assessment of any open JPEG image. A green light in the panel indicates that the file matches a verified original signature in FourMatch software’s extensive and growing database of more than 70,000 signatures. If a match is not found, the panel displays any relevant information that can aid the investigator in further assessing the photo’s reliability.
Check it out in action, and see also coverage in the NY Times:
One other neat detail:
Fourandsix will donate 2 percent of their proceeds from the sale of this software to the National Center for Missing & Exploited Children (NCMEC). The donation will support NCMEC efforts to find missing children and prevent the abduction and sexual exploitation of children.

Using Kinect to turn objects into puppets
KinÊtre is a research project from Microsoft Research Cambridge that allows novice users to scan physical objects and bring them to life in seconds by using their own bodies to animate them. This system has a multitude of potential uses for interactive storytelling, physical gaming, or more immersive communications.
“When we started this,” says creator Jiawen Chen, “we were thinking of using it as a more effective way of doing set dressing and prop placement in movies for a preview. Studios have large collections of shapes, and it’s pretty tedious to move them into place exactly. We wanted to be able to quickly walk around and grab things and twist them around. Then we realized we can do many more fun things.” I’ll bet.
Pretty darn cool, though if that Kinect dodgeball demo isn’t Centrifugal Bumble-Puppy come to life, I don’t know what is.

Adobe & MIT team up on Halide, a new imaging language
Last month I broke the somewhat sad news that Adobe’s Pixel Bender language is being retired, but for a good cause: we can now redirect effort & try other ways to achieve similar goals. To that end, Adobe researchers have teamed up with staff at the Massachusetts Institute of Technology to define Halide, a new programming language for imaging. It promises faster, more compact, and more portable code.
According to MIT News,
In tests, the MIT researchers used Halide to rewrite several common image-processing algorithms whose performance had already been optimized by seasoned programmers. The Halide versions were typically about one-third as long but offered significant performance gains — two-, three-, or even six-fold speedups. In one instance, the Halide program was actually longer than the original — but the speedup was 70-fold.
Hot damn. #progress

Exaggerating motion in video
Normally we work so hard to reduce motion in video (e.g. bringing the awesome Warp Stabilizer from After Effects to Premiere Pro CS6). There are cases, though (e.g. monitoring a heartbeat, or the breathing of a baby) where one wants to do just the opposite. Here’s an interesting demo:

New Adobe tech for making cinemagraphs
Now Adobe researcher Aseem Agarwala & colleagues at UC Berkeley have devised “a semi-automated technique for selectively de- animating video to remove the large-scale motions of one or more objects so that other motions are easier to see.” It’s easier seen than described:
From the project site:
The user draws strokes to indicate the regions of the video that should be immobilized, and our algorithm warps the video to remove the large-scale motion of these regions while leaving finer-scale, relative motions intact. However, such warps may introduce unnatural motions in previously motionless areas, such as background regions. We therefore use a graph-cut-based optimization to composite the warped video regions with still frames from the input video; we also optionally loop the output in a seamless manner.
Our technique enables a number of applications such as clearer motion visualization, simpler creation of artistic cinemagraphs (photos that include looping motions in some regions), and new ways to edit appearance and complicated motion paths in video by manipulating a de-animated representation. We demonstrate the success of our technique with a number of motion visualizations, cinemagraphs and video editing examples created from a variety of short input videos, as well as visual and numerical comparison to previous techniques.

“Photoshopped or Not? A Tool to Tell”
My longtime boss Kevin Connor left Adobe earlier this year to launch a startup, Fourandsix, aimed at “revealing the truth behind every photograph.” Now his co-founder (and Adobe collaborator) Hany Farid has published some interesting research:
Dr. Farid and Eric Kee, a Ph.D. student in computer science at Dartmouth, are proposing a software tool for measuring how much fashion and beauty photos have been altered, a 1-to-5 scale that distinguishes the infinitesimal from the fantastic. Their research is being published this week in a scholarly journal, The Proceedings of the National Academy of Sciences.

Exhibit: Photo Tampering Throughout History
You can build a business manipulating photos; how about building one by detecting those manipulations?
My longtime boss Kevin Connor was instrumental in building Photoshop, Lightroom, and PS Elements into the successes they are today, and he taught me the ropes of product management. After 15 years he was ready to try starting his own company, so this spring he teamed up with Dr. Hany Farid (“the father of digital image forensics,” said NOVA). Together they’ve started forensics company Fourandsix (get the pun?), aimed at “revealing the truth behind every photograph.”
Now they’ve put up Photo Tampering Throughout History, an interesting collection of famous (and infamous) forgeries & manipulations from Abraham Lincoln’s day to the present. Numerous examples include before & after images plus brief histories of what happened.

Todor talks plenoptic imaging
Recently we and others have gained deeper understanding of the fundamentals of the plenoptic camera and Lippmann sensor. As a result, we have developed new rendering approaches to improve resolution, remove artifacts, and render in real time. By capturing multiple modalities simultaneously, our camera captures images that are focusable after the fact and which can be displayed in multi view stereo. The camera can also be configured to capture HDR, polarization, multispectral color and other modalities. With superresolution techniques we can even render results that approach full sensor resolution. During our presentation we will demonstrate interactive real time rendering of 3D views with after the fact focusing.

Developers at the Max Planck Institute for Informatics in Saarbrücken, Germany compiled 3D scans of 120 men and women of varying sizes, merging them into a single model that can be morphed to any shape and overlaid atop original footage.
The software, called MovieReshape, builds on existing programs that track an actor’s silhouette through a scene, mapping the body into a morphable model. Using the compiled 3D scans, the program can create realistic-looking and moving body parts to the programmer’s specifications.

Video: “A computational model of aesthetics”
People always like to joke about Photoshop eventually adding a big red “Make My Photo Good” button, automatically figuring out what looks good & what adjustments are needed. Of course, researchers are working on just that sort of thing:
As someone who aspires to be creative, I have mixed feelings. The idea of rating images according to precomputed standards of beauty makes me think of the Robin Williams character in Dead Poets Society excoriating a textbook that rated poetry along two axes:
Excrement! That’s what I think of Mr. J. Evans Pritchard! We’re not laying pipe! We’re talking about poetry. How can you describe poetry like American Bandstand? “I like Byron, I give him a 42 but I can’t dance to it!”
And yet, I find I’m intrigued by the idea, wanting to run the algorithm on my images–if only, maybe, to have fun flouting it. I also have to admit that I’d like to see the images taken by certain of my family members (not you, hon) run through such algorithms–if only to crop in on the good stuff.

Adobe previews “Infinite Images” technology
Remember Shai Avidan, the co-creator of seam carving (Content-Aware Scaling) who joined Adobe last year? Just as he did at Adobe MAX last year, Shai took to the stage this year with an eye-catching demo. Collaborating with Prof. Bill Freeman and a team from MIT, Shai has been working on "Infinite Images," "a system for exploring large collections of photos in a virtual 3D space." The team writes:
Our system does not assume the photographs are of a single real 3D location, nor that they were taken at the same time. Instead, we organize the photos in themes, such as city streets or skylines, and let users navigate within each theme using intuitive 3D controls that include pan, zoom and rotate…
We present results on a collection of several millions of images downloaded from Flickr and broken into themes that consist of a few hundred thousands images each. A byproduct of our system is the ability to construct extremely long panoramas, as well as image taxi, a program that generates a virtual tour between a user supplied start and finish images.
To read up on some details, check out the PDF (shared via Acrobat.com):
You could also visit Shai’s site to read up on “Non-Parametric Acceleration, Super-Resolution, and Off-Center Matting,” not to mention “Part Selection with Sparse Eigenvectors”–but I’d recommend being a lot smarter than I am. ;-) (We just may have to name our next child “Eigenvector.”)

Hot image science o’ the day
Pravin Bhat & friends at the University of Washington have put together a rather eye-popping video that demonstrates Using Photographs to Enhance Videos of a Static Scene. I think you’ll dig it. (The removal of the No Parking sign is especially impressive.) [Via Jeff Tranberry]
The work builds upon research by Adobe’s Aseem Agarwala (who was instrumental in bringing Auto-Blend to Photoshop CS3). Adobe Senior Principal Scientist (and UW prof.) David Salesin is helping facilitate more collaboration between Adobe teams & academia, recruiting full-time hires like Aseem & sponsoring visiting researchers like Hany Farid.
(Note: As always, please don’t take my mentioning of various tech demos as a hint about any specific feature showing up in a particular Adobe product. I just post things that I find interesting & inspiring.)

Cool painting tech demo o’ the day
Photoshop engineer Jerry Harris is responsible for the application’s painting tools, and he’s always got an eye open for interesting developments in the field of computerized painting. This morning he passed along a cool demo video of James McCann and Nancy Pollard’s Real-time Gradient-domain Painting technology.
In a nutshell, according to the video, "A gradient brush allows me to paint with intensity differences. When I draw a stroke, I am specifying that one side is lighter than the other." Uh, okay… And the video is a little ho-hum until the middle. That’s when things get rather cool. Check out cloning/duplicating pixels along a path, plus the interesting approach to painting a band of color.

Imaging heavy hitters join Adobe
A number of rock stars from the world of image science have recently joined Adobe:
- That crazy-cool image resizing demo I mentioned last week continues to get all kinds of attention. I was therefore happy to learn that co-creator Shai Avidan joined the Adobe office in Newton, MA (just down the ‘pike from MIT) last Monday. Here’s a bit more info and Shai’s photo.
- Wojciech Matusik began work at Adobe in May. He’s done some really cool work in the emerging fields of multi-aperture photography, 3D TV, and much more. Like Shai, he works from the Newton office.
- Sylvain Paris is due to join Adobe in a couple of weeks. He’s worked on techniques for matching tones across photos ("Make my image pop like Ansel’s"), generating 3D data from 2D captures, and more. His paper on bilateral filtering was written with MIT colleagues Jiawen Chen (who interned this summer at Adobe) and Fredo Durand.
Adobe Senior Principal Scientist David Salesin, who manages this crew, notes that "If you count their SIGGRAPH papers as well, you’ll see that current Adobe employees had 11 of the 108 papers in the conference."
Now, let me inject a disclaimer: Just because a particular researcher has worked on a particular technology in his or her past life, it’s not possible to conclude that a specific feature will show up in a particular Adobe product. How’s that for non-commital? ;-) In any case, it’s just exciting that so many smart folks are joining the team (more brains to hijack!).

“Holy crap”-worthy imaging technology
Wow–now this I haven’t seen before: Israeli brainiacs Shai Avidan and Ariel Shamir have created a pretty darn interesting video that demonstrates their technique of "Seam Carving for Content-Aware Image Resizing." When scaling an image horizontally or vertically (e.g. making a panorama narrower), the technology looks for paths of pixels that can be removed while causing the least visual disruption. Just as interesting, if not more so, I think, is the way the technology can add pixels when increasing image dimensions. Seriously, just check out the video; I think you’ll be blown away. (More info is in a 20MB PDF, in which they cite work by Adobe’s Aseem Agarwala–the creator of Photoshop CS3′s Auto-Blend Layer code.) [Via Geoff Stearns]
I hope to share more good stuff from SIGGRAPH soon. While I was being stuffed with ham sandwiches by kindly Irish folks, a number of Adobe engineers were speaking at & exploring the show. Todor Georgiev, one of the key minds behind the Healing Brush, has been busily gluing together his own cutting edge optical systems. More on that soon.

Digital imaging goes to court
CNET reported recently on a court case that involved image authentication software as well as human experts, both seeking to distinguish unretouched photographs from those created or altered using digital tools. After disallowing the software, written by Hany Farid & his team at Dartmouth, the judge ultimately disallowed a human witness, ruling that neither one could adequately distinguish between real & synthetic images. The story includes some short excerpts from the judge’s rulings, offering some insight into the legal issues at play (e.g. "Protected speech"–manmade imagery–"does not become unprotected merely because it resembles the latter"–illegal pornography, etc.).
As I’ve mentioned previously, Adobe has been collaborating with Dr. Farid & his team for a few years, so we wanted to know his take on the ruling. He replied,
The news story didn’t quite get it right. Our program correctly classifies about 70% of photographic images while correctly classifying 99.5% of computer-generated images. That is, an error rate of 0.5%. We configured the classifier in this way so as to give the benefit of the doubt to the defendant. The prosecutor decided not to use our testimony because of other reasons, not because of a high error rate.
The defense argues that the lay person cannot tell the difference between photographic and CG images. Following this ruling by Gertner, we performed a study to see just how well human subjects are at distinguishing. They turn out to be surprisingly good. Here is a short abstract describing our results. [Observers correctly classified 83% of the photographic images and 82% of the CG images.]
