Abstract

A CAM-based (Content Addressable Memory) image matching system is implemented on hardware system using FPGA. The system has simple structure, does not employ any Central Processor Units (CPUs) as well as complicated computations. The authors take advantages of CAM which has an ability of parallel multi-match mode for designing the system. Thus increases the matching performance of the system. The system is applied for exact image matching or approximate image matching with various required search patterns without using search principles. In this paper, the authors present the system for fast image matching applications on 2-D data.
