Google Earth Facade Shadow Removal by Mei Han, Vivek Kwatra, and Shengyang Dai
We will demonstrate our technique for removing shadows and other lighting/texture artifacts from building facades in Google Earth. We obtain cleaner, clearer, and more uniform textures which provide users with an improved visual experience.

Video Stabilization on YouTube Editor by Matthias Grundmann, Vivek Kwatra, and Irfan Essa
Casually shot videos captured by handheld or mobile cameras suffer from significant amount of shake. In contrast, professionally shot video usually employs stabilization equipment such as tripods or camera dollies, and employ ease-in and ease-out for transitions. Our technique mimics these cinematographic principles, by optimally dividing the original, shaky camera path into a set of segments and approximating each with either constant, linear or parabolic motion using a computationally efficient and stable algorithm. We will showcase a live version of our algorithm, featuring real-time performance and interactive control, which is publicly available at youtube.com/editor.

Tag Suggest for YouTube by George Toderici and Mehmet Emre Sargin
YouTube offers millions of users the opportunity to upload videos and share them with their friends. Many users would love to have their videos discoverable but don't annotate them properly. One new feature on YouTube that seeks to address this problem is tag prediction based on video content and independently based on text metadata.
