Fingerprint fractal compression based on direction information
Wenyuan Wang · Journal of Tsinghua University(Science and Technology) · 1998
Fingerprint is one of the important information in identification. It has practicable meaning to compress fingerprint in storage. This paper presents a new image compression method based on fingerprint direction information. At first divide fingerprint into several blocks according to their direction, and then arrange each block image data into a serial data. Using fractal compression to encode the one dimension data. This method solves the difficulty of fractal image compression. It achieves a high compress ratio and encode speed, low distortion of recover image. Experiment result shows the advantage of the new method.
