A novel DCT and FTC based hybrid still image compression algorithm
Jiangtao Wen, Xuelong Zhu · 2002
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.
