Abstract
This review briefly discusses processes that have been suggested in the last 25Â years as important to the intermediate stages of visual processing of patterns. Five categories of processes are presented: (1) Higher-order processes including FRF structures; (2) Divisive contrast nonlinearities including contrast normalization; (3) Subtractive contrast nonlinearities including contrast comparison; (4) Non-classical receptive fields (surround suppression, cross-orientation inhibition); (5) Contour integration.
Research highlights⺠Reviews last 25 years of research on pattern vision. ⺠Particular emphasis on models for intermediate-level visual processes. ⺠Suggests five categories of useful non-linear additions to earlier linear models.
