The Effect of Quantization Process on FIC for Gray Image Using Traditional Method
Abstract
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.
