Abstract :
Quadtree region representation, image properties computation of binary image and moment invariants are implemented on a pyramid machine. Based on those algorithms a parallel pattern recognition technique is proposed. Exploiting the parallel quadtree representation on pyramid machine, moment invariants seems to be a good descriptor in a hierarchical coarse-fine matching strategy. For a particular image, the moment invariants always changes slightly at higher levels in the representation. A matching criteria of distance measure can be used to find dissimilarity in images
