Abstract :
A modified fractal transform (MFT) is presented. In the function part of the MFT, the conventional greyscale function of an image block is replaced by the greyscale function of an error image block whose mean is removed. This fractal transform is used to approximate an image which is to be encoded. The simulation results show that with the MFT the image decoding process is very fast, typically only 1 to 3 iterations are required to reconstruct the image while the quality of reconstructed image remains high
