Abstract :
A novel discrete cosine transform (DCT) and fractal transform coding (FTC) hybrid image compression algorithm is proposed which dramatically improves the speed of the FTC coding and JPEG´s ability of preserving image details at high compression ratios. The overall subjective quality of the whole JPEG decoded image is also heightened
