Abstract: With the development of information network and multimedia technology, digital image, as a kind of the most important media, is used much widely. Image compression becomes more and more important for great deal of data. In this paper, some most popular compression algorithms: JPEG, Fractal compression and Wavelet compression are introduced, the advantages, disadvantages and developments of these algorithms are discussed, and some other compression algorithms are mentioned. Then an algorithm is indicated that using Polar-Log coordinate mapping as a preprocessor, which simulates the characteristic of human visual, a higher compression rate can be obtained. Finally, the conclusions and expectations of image compression algorithms are given.
