Learning where to look in 360 environments

Professor Kristen Grauman (University of Texas at Austin)
Abstract / Description: 

Many vision tasks require not just categorizing a well-composed human-taken photo, but also intelligently deciding "where to look" in order to get a meaningful observation in the first place. We explore how an agent can anticipate the visual effects of its actions, and develop policies for learning to look around actively---both for the sake of a specific recognition task as well as for generic exploratory behavior. In addition, we examine how a system can learn from unlabeled video to mimic human videographer tendencies, automatically deciding where to look in unedited 360 degree panoramas. Finally, to facilitate 360 video processing, we introduce spherical convolution, which allows application of off-the-shelf deep networks and object detectors to 360 imagery.
