Abstract:
The estimation of motion direction from time varying images is a fundamental task of both biological and artificial visual systems. Directional selective neurons are found in all species; moreover, in many of them, direction of motion is signaled already at the output of retina being carried to higher brain areas. Here we use simple schemes to investigate how directional selectivity changes for cells postsynaptic to retinal neurons. We show how sharpening in directional selectivity is achieved...     »
