DCT and fractal compression incorporate certain advantages and disadvantages. In the present communication, a hybrid fractal/DCT image compression technique is presented. DCT is employed whenever the quality of the decoding block is of sufficient quality or else fractal compression technique is used for the encoding that will also lead to great compression. Pruned DCT is used to lower even more the computational time. The result is faster coding than fractals, better compression ratios than the DCT and better image quality from both techniques.
