Prediction on decoded image quality for fractal image coding
Sheng Bi · Journal of Computer Applications · 2010
A new decoded image quality prediction algorithm for fractal image coding was proposed.According to the results of many experiments,there exists an approximately exponential discipline between the average collage error and the PSNR of decoded image quality.The collage error of each range block was computed in the fractal encoding process and the PSNR of decoded image quality was predicted according to the average collage error.The experimental results show that for different sizes of range blocks and fast fractal image encoding,the proposed algorithm can obtain satisfying prediction results of decoded image quality.
