Visual motion boundaries provide a powerful cue for the perceptual organization of scenes. Motion boundaries are present when surfaces in motion occlude one another. Conventional approaches to motion analysis have relied on assumptions of data conservation and smoothness, which has made analysis of motion boundaries diicult. We show that a common source of(More)

Many representations in early vision can be constructed by performing orientation analysis along several sampling dimensions. Texture is often oriented in space, motion is oriented in space-time, and stereo is oriented in spacedisparity. In these modalities, we can construct distributed representations with oriented energy measures used in models of(More)
