Abstract:

Visual perception was investigated using spatial filters that are constrained by biological data. This report has four major parts 1 a theoretical background to Fourier analysis 2 a review of the literature relating to the spatial filtering characteristics of mammalian visual systems 3 visual information processing in terms of spatial filtering 4 the relating of contrast sensitivity to the identification of complex objects. The common denominator to all the investigations is spatial filtering. The major goal of the dissertation was the attempt to explain certain aspects of visual perception using a single concept filtering. Author
