| Abstract | ||
| this work is show the effect of quantization on the reconstructed image in fractal image compression FIC method. it is based on zero-mean block matching method, at this method the mean of the range blocks is used instead of traditional offset parameter. This reduces and simplifies the computations of the affine parameters during the encoding process. 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 (69.6%) and encoding time about (18.6%) but the decreases of PSNR around (0.3%), The quality of the reconstructed image is good either we use the quantization process or not used it. | ||
