摘要: From psychophysics it is known that humans easily perceive motion in Fourier-stimuli which dots are displaced coherently into one direction. Furthermore, can be extracted from Drift-balanced stimuli the on average have no distinct direction of motion, or even paradox Θ-motion where opposite to perceived motion. Whereas Fourier-motion explained by very basic detectors and nonlinear preprocessing input account for detection a hierarchical model with two layers was proposed explain perception Θ-motion. The well described visual system fly allows investigate whether these complex detected comparatively simple brain.
