| Research Abstract |
Computational models of the early visual system were proposed based on theoretical analysis of spatio-temporal derivatives :(i) receptive fields of V1 neurons selective to binocular disparity, and(ii) selective to speed of moving stimuli. Moreover,(iii) a novel computational theory and a model of MT neurons were also derived from the theoretical analysis of the model(i) and(ii) above. As results of this MT research, complex neural properties of MT neurons and perceptual properties affected by image contrast were successfully accounted for by the single model of MT neurons. Software platform(s) have been developed to make computational research be more sustainable for large scale simulation of vision.
