12 January 1977 Optical Spatial Channel And Image Encoding Principle
Author Affiliations +
From Gabor's concept of information and Shannon's discrete channel, the capacity of an optical spatial channel is calculated. We have illustrated two basic spatially image encoding processes; namely, the encoding over a set of uniform resolution cells, and over a set of nonuniform resolution cells. One of the important results is that the most efficient image encoding is the one that provides the most probable encoded irradiance distribution over the spatial channel.
