in this work we study the effect of quantization process on the reconstructed image in fractal image compression FIC method. This method is tested on 8 bits/pixel gray image. The test results conducted on Lena image indicated that the quantization increases compression ratio about (65.8%) and encoding time about (17.1%) but the decreases of PSNR around (1.73%), The quality of the reconstructed image is good either we use the quantization process or not.
