Proposes a method of moving object matching based on color characteristics. Defines main color region of moving object by color histogram, and establishes RGB 3D color space fuzzy subset of the main color region on the basis of maximum membership grade principle. Finally compares fuzzy membership function and fuzzy nearness function of the matching and to match object by means of fuzzy similar matching principle. The experimental results show that the approach is viable and reliable to solve the problem of moving object matching in video monitoring.
