Abstract

A hierarchical and recursive system for classifying, identifying, describing and analyzing images and the related apparatus are disclosed wherein a digital image is partitioned into subarrays, the content of each subarray is compared to memory elements stored within memory, and if a match occurs, the name of the matched memory element is assigned to the subarray. When all subarrays have been named, a symbolic image whose pixel elements are the assigned names, is formed which is the image for the next level of identification. If no match occurs, a new memory element and appropriate corresponding name are created and added to the memory stack.
