Realization of character recognition by means of joint transform
The correlation property of the joint transform is utilized and the parallel recognition of tho multiplying character signals is analysed and realized. The experiments show that the process gives a high signal to noise ratio and a good sensitivity. The method is much simple and practical than the conversional matched filter method for the character recognition.
