Analysis of Visual Motion

Visual motion is a compelling cue to the structure of the world around us. In a series of related work, we have developed methods for determining optical flow in the presence of discontinuities, extracting shape properties in a qualitative manner that avoids much of the complexity and noise sensitivity of traditional structure-from-motion methods, and detecting moving objects in the environment when the sensor might also be moving.
