Research on the Algorithm for Computing Rendered Images of Fingerprint

By research on the algorithm for computing rendered images of fingerprint, IFS model of image expression is set up, and the steps and the methods about the recognition of the characteristics of fingerprint image basing on encode of iterated function system are put forward as well. With the model and the computing similar parameter between source image and result image, the characteristics of fingerprint image can be quickly acquired. Thus, the recognition of fingerprint image can be realized. The result of the example indicates that the computing velocity of IFS model is 5~10 times quicker than the traditional image matrix digital image. Meanwhile, the ratio of its recognition reaches to 99.86 percent. IFS model produces a fairly good effect by application on the identity authentication at the entrance of a network user on the platform of information network under WEB.
