Fractal Compression Coding Based on Fractal Dimension Feature Blocks

The paper associates fractal dimension with the image disorder degree, which is introduced into pre-classification for fractal compression coding process together with the concept of quartered-tree coding, then a fractal compression coding approach based on fractal dimension feature blocks is brought forward. The algorithm improves coding time, compression ratio, but the peak-peak signal-noise ratio suffers a little. The validity of the algorithm verifies by the experiments.
