The thesis illustrates the development of DSP-based systems-¡§Hand Written Number Recognition System,¡¨ and ¡§Pattern Recognition System.¡¨ Hand written number recognition system consists of three sub-systems and recognition algorithm: Image Acquisition System, Image Preprocessing System, Image Segmentation System and Binary Pattern Match Algorithm. Pattern recognition system, as well, consists of three sub-systems and recognition algorithm: Image Acquisition System, Image Preprocessing System, Image Segmentation System, and Visual Dynamic Time Warping Algorithm. From the result of the experiment, both DSP image recognition systems can meet the expectation and gain good recognition and efficiency.
