Announcing the new Interdisciplinary Research Center for Machine Learning at Georgia Tech (ML@GT)

October 6th, 2016 Irfan Essa Posted in In The News, Interesting, Machine Learning No Comments »

Announcement from Georgia Tech’s College of Computing about a new Interdisciplinary Research Center for Machine Learning (ML@GT) that I will be serving as the Inaugural Director for.ML@GT

Machine Learning @ Georgia Tech Based in the College of Computing, ML@GT represents all of Georgia Tech. It is tasked with pushing forward the ability for computers to learn from observations and data. As one of the fastest growing research areas in computing, machine learning spans many disciplines that use data to discover scientific principles, infer patterns, and extract meaningful knowledge.

According to School of Interactive Computing Professor Irfan Essa, inaugural director of ML@GT, machine learning (ML) has reached a new level of maturity and is now impacting all aspects of computing, engineering, science, and business. “We are in the era of aggregation, of collecting data,” said Essa. “However, machine learning is now propelling data analysis, and the whole concept of interpreting that data, toward a new era of making sense of the data, using it to make meaningful connections between information, and acting upon it in innovative ways that bring the most benefit to the most people.”

The new center begins with more than 100 affiliated faculty members from five Georgia Tech colleges and the Georgia Tech Research Institute, as well as some jointly affiliated with Emory University.

Research Blog: Motion Stills – Create beautiful GIFs from Live Photos

June 7th, 2016 Irfan Essa Posted in Computational Photography and Video, Computer Vision, In The News, Interesting, Matthias Grundmann, Projects No Comments »

Kudos to the team from Machine Perception at Google Research that just launched the Motion Still App to generate novel photos on an iOS device. This work is in part aimed at combining efforts like Video Textures and Video Stabilization and a lot more.

Today we are releasing Motion Stills, an iOS app from Google Research that acts as a virtual camera operator for your Apple Live Photos. We use our video stabilization technology to freeze the background into a still photo or create sweeping cinematic pans. The resulting looping GIFs and movies come alive, and can easily be shared via messaging or on social media.

Atlanta Magazine Features, Thad Starner, “Magnifying glass”

March 3rd, 2014 Irfan Essa Posted in In The News, Thad Starner, Ubiquitous Computing No Comments »

A wonderful write up on my friend and colleague, Thad Starner in the Atlanta Magazine.  Worth a read for sure

“The guy with the computer on his face.” This would have been a fair description of Starner at almost any time over the past twenty years. He first built his own wearable computer with a head-mounted display in 1993, and has donned some version or another of the computer-eyepiece-Internet system most days since then. But over the previous year, something changed.

Google I/O 2013: Secrets of Video Stabilization on YouTube

May 28th, 2013 Irfan Essa Posted in Computational Photography and Video, Google, In The News, Matthias Grundmann, Presentations, Vivek Kwatra No Comments »

Presentation at Google I/0 2013 by Matthias Grundmann, John Gregg, and Vivek Kwatra on our Video Stabilizer on YouTube

Video stabilization is a key component of YouTubes video enhancement tools and All YouTube uploads are automatically detected for shakiness and suggested stabilization if needed. This talk will describe the technical details behind our fully automatic one-click stabilization technology, including aspects such as camera path optimization, rolling shutter detection and removal, distributed computing for real-time previews, and camera shake detection.

AT HIGH Museum/Lumière’s Fall Lecture and Panel Discussion on “Art In The Digital Culture… Threat or Opportunity?”

September 8th, 2012 Irfan Essa Posted in Computational Photography and Video, In The News, Presentations No Comments »

Wednesday September 19, 2012, 7:00pm in the Hill Auditorium, High Museum, Altanta.

In this sixth installment of Lumière’s Fall Lecture Series, Shannon Perich, curator of the photographic history collection at the National Museum of American History, Smithsonian Institution, and Irfan Essa of the Georgia Institute of Technology will each speak to the future of art in a rapidly expanding digital culture. Their commentary will be followed by a panel discussion with audience participation. The panel will address the threats and opportunities created by a growing range of capabilities to create, distribute, and interact with art. Additional information is available at lecture is a collaborative event with the Atlanta Celebrates Photography 2012 Festival.

Video Stabilization on YouTube

May 6th, 2012 Irfan Essa Posted in Computational Photography and Video, Google, In The News, Matthias Grundmann, Vivek Kwatra No Comments »

Here is an excerpt from a Google Research Blog on our Video Stabilization on YouTube.  Now even more improved.

One thing we have been working on within Research at Google is developing methods for making casual videos look more professional, thereby providing users with a better viewing experience. Professional videos have several characteristics that differentiate them from casually shot videos. For example, in order to tell a story, cinematographers carefully control lighting and exposure and use specialized equipment to plan camera movement.

We have developed a technique that mimics professional camera moves and applies them to videos recorded by handheld devices. Cinematographers use specialized equipment such as tripods and dollies to plan their camera paths and hold them steady. In contrast, think of a video you shot using a mobile phone camera. How steady was your hand and were you able to anticipate an interesting moment and smoothly pan the camera to capture that moment? To bridge these differences, we propose an algorithm that automatically determines the best camera path and recasts the video as if it were filmed using stabilization equipment.

YouTube effects: Shake it like an Instagram picture

via YouTube effects: Shake it like an Instagram picture — Online Video News.

YouTube users can now apply a number of Instagram-like effects to their videos, giving them a cartoonish or Lomo-like look with the click of a button. The effects are part of a new editing feature that also includes cropping and advanced image stabilization.

Taking the shaking out of video uploads should go a long way towards making some of the amateur footage captured on mobile phones more watchable, but it can also be resource-intensive — which is why Google’s engineers invented an entirely new approach toward image stabilization.

The new editing functionality will be part of YouTube’s video page, where a new “Edit video” button will offer access to filters and other editing functionality. This type of post-processing is separate from YouTube’s video editor, which allows to produce new videos based on existing clips.
