Abstract
The complexity of the visual world makes it difficult for computer vision to understand images and for computer graphics to synthesize visual content. The traditional computer vision or computer graphics pipeline mitigates this complexity with a bottom up, divide and conquer strategy (e.g. segmenting then classifying, assembling part-based models, or using scanning window detectors). In this talk I will discuss research that is fundamentally different, enabled by the observation that while the space of images is infinite, the space of "scenes" might not be astronomically large. With access to imagery on an Internet scale, for most images there exist numerous semantically and structurally similar scenes. My research is focused on exploiting and refining large scale scene matching to short circuit the typical computer vision and graphics pipelines for tasks such as scene completion, image geolocation, object detection, and high interest photo selection.
