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

Eman A. Al-Hilo, Kawther H. Al-khafaji

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.
