| Abstract: | This paper evaluate the lossless and lossy compressions of medical images.Several lossless compression methods developed in the recent years are introduced briefly.As lossy compression methods,the wavelet and fractal compression technologies are described in detail.Under the assurance of high quality of medical images,a combination of lossless and lossy compressions is made with a higher compression rate. |
