Neural computations in some visual processes

Neural computations reported earlier by the author and coworkers (1988) are extended to more complex visual phenomena by introducing anisotropic receptive fields and using three-dimensional graphs, contour plots, and gray-scale plots. Evolutions of neural activities in image processing in the visual system are simulated. Activity is achieved in 25 ms. It is felt that the visual system operates as a nonlinear 2-D spatio-temporal finite-extent impulse response filter.
