We present a new FFT-based technique of fractal image compression which can significantly speed up the process of matching domain and range blocks. In this method the isometric transformations of a domain block are chosen to permit block matching trough cross correlation of range and domain blocks, which is implemented trough the FFT. A suboptimal choice of domain blocks by performing a magnitude Fourier domain comparison of the range and domain blocks prior to correlation further speeds up the block matching process.
