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.
