Recently, digital image apparatus such as CT, MRI, US are used in medical diagnosis. Cathode Ray Tube (CRT) diagnosis is now accepted in some clinical situations because of improvements of display technology. A generalization of the two-dimensional random checkerboard process is described and we developed a new calculation method for correlation in any directions around contiguous square regions permitting a continuous gray levels. Autocorrelation function of this model is obtained. Theoretical autocorrelation function and Wiener spectrum are calculated using this model.
