A VLSI architecture for hierarchical scene matching

Scene matching is the problem of matching regions of two images of the same scene taken by different sensors at different times or under different viewing conditions. Hierarchical scene matching generates a multiresolution pyramid of the images to be matched. The authors describe hierarchical scene matching technique, related work and their proposed VLSI architecture. They present a description of the three subsystems-pyramid generation block, exhaustive search block and template match block. Then they briefly describe the performance attainable with the proposed architecture which uses a large amount of parallelism and pipelining
