简介
When a static textured background is covered and uncovered by a moving bar of the same mean luminance we can clearly see the motion of the bar. Texture‐defined motion provides an example of a naturally occurring second‐order motion. Second‐order motion sequences defeat standard spatio‐temporal energy models of motion perception. It has been proposed that second‐order stimuli are analysed by separate systems, operating in parallel with luminance‐defined motion processing, which incorporate identifiable pre‐processing stages that make second‐order patterns visible to standard techniques. However, the proposal of multiple paths to motion analysis remains controversial. Here we describe the behaviour of a model that recovers both luminance‐defined and an important class of texture‐defined motion. The model also accounts for the induced motion that is seen in some texture‐defined motion …
