医学图像无损压缩与有损压缩技术的进展

Development of lossless and lossy compression for medical images

本文对医学图像无损压缩和有损压缩的概念和应用进行了分析比较 ,并简要介绍了几种近年来发展的图像无损压缩方法 ,重点介绍了有损压缩中的小波图像压缩技术和分形图像压缩技术。在医学图像的压缩中 ,通过有效地结合无损压缩和有损压缩技术 ,可以在得到医学要求的图像保真度的前提上 。

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.
