Claim One:
1. A system for compressing and decompressing image data signals representing an original image characterized by p(x,y), where x and y are the spatial coordinates of pixels of the image, which system comprises: (a) means to convolve said image data signals with coded random pattern data signals generated according to a blurring function ##EQU11## where N is an integer greater than one and x.sub.n and y.sub.n are the positions of delta-function impulses, x.sub.n and y.sub.n being chosen from distributions characterized by probability density functions, to provide convolved data signals representing a blurred image; (b) means to compress said convolved data signals to permit efficient storage or transmission of the information in said original image; and (c) means to recover said original image from said convolved compressed data signals with a function which is the inverse of said compressing means and said coded blurring means to provide data signals representing said original image in restored form.
