Optical joint transform correlation identifies the similarity degree between reference image and target image according to the correlation peak appearance in correlation plane by its correlation operation. Different from the common fingerp rint recognition method on the princip le of the detail spot coordinatesmatching, the novel fingerp rint iden tification algorithm based on joint transform correlation is efficient and quickly because it depends upon the integrated feature of fingerp rint images and has the less relatively demand to the image quality. The recognizing result to finger print database by computer proves the feasibility of the method.
