This paper describes how the Fractal image coding takes the long time in its computation. It is its block searching and matching which takes long time. So to overcome this, the authors use the combination of fractal and wavelet this reduces the computation time. Based on this, they proposed an improved fractal image algorithm based on the wavelet subtree. The algorithm proposed improved fractal image compression technique in wavelet domain with thresholding value. This reduces the encoding time effectively.
