So, rather than defining motion based on its physical characteristics. To provide insights into computational mechanisms of motion perception, in addition to psychophysics and neurosciences, we review machine vision studies seeking to solve similar problems. This chapter covers these various functional roles of motion perception. We then consider possible linking mechanisms of the two levels and propose intrinsic flow decomposition as the key problem. More importantly, the ability to process. Using behavioral genetic methodology, we demonstrate that genes contribute to interindividual variation in BM perception abilities and autistic traits. Although there are many motion interpretation processes, we highlight the recent progress in research on the perception of material (e.g., specular reflection, liquid viscosity) and on animacy perception. Impaired visual processing of biological motion (BM) is inextricably linked to compromised social cognitive abilities in autism spectrum disorder (ASD). Perceiving Motion Motion perception is the process of inferring the speed and direction of elements in a scene based on visual input. In the higher level, the velocity map is interpreted. Although the model based on V1-MT physiology provides a good computational framework for this level of processing, it needs to be updated to fully explain psychophysical findings about motion perception, including complex motion signal interactions in the spatiotemporal-frequency and space domains.

A variety of mechanisms contribute to visual motion processing.

In the lower level, local motion signals are detected by spatiotemporal-frequency-selective sensors and then integrated into a motion vector flow. Motion is one of a few major sensory attributes of visual processing. Visual motion processing can be conceptually divided into two levels.
