MATLAB小波工具箱在医学图像压缩中的应用

Application of wavelet toolbox in medical image compression

目的本文分析了数据压缩的必要性,说明了如何利用Matlab软件中小波工具箱对图像进行分解与重构,通过实现对医学图像的压缩,对不同阈值下采用不同的小波压缩的结果进行了比较和讨论。

The text analyzed the necessity of the data compressing and explai ned the method of medical image decompostion and reconstuction by wavelet toolbo x; by compressing the medical image, proceeded comparison and discussion of the result of compressing by different threshold.
