A Hybrid Scheme Coding Using SPHIT and Fractal for Mammography Image Compression

Medical imaging techniques produce very large amounts of data, that have to be transmitted or stored, and therefore, there is a need for image compression. Fractal image compression still suffers from a high encoding time. We propose a new optimization approach to reduce the time of fractal image encoding. This approach is a hybridization of the SPIHT algorithm and Jacquin-style coding scheme. Our approach was tested on mammography images of MIAS database.
