Computational Vision

In the computational aspects of simulation of vision, investigation of the center-surround model of low-level vision was carried out resulting in a proposed model. This model, which takes into account the recent physiological findings of retinal circuitry regarding “extra classical receptive field” and the presence of very narrow channels, is capable of retaining shading information, in the sense of stochastic halftone process, in the zero-crossing map. Contrary to the popular belief, this model, probably for the first time, suggest that several illusions like Simultaneous Brightness-Contrast, White Effect, Herman Grid, Todorovic Effect etc. could be explained by low-level computational model.
