摘要
医学图像数据量巨大,在传输和图像质量方面,不同人群在使用医学图像时对图像有不同的需求。本文比较了基于DCT的JPEG压缩方法和基于DWT的JEPG2000压缩方法,并用MAT-LAB进行了仿真实验,将压缩后的图像在图像质量及大小两方面与原始图像作了对比。医务人员可选用不同的压缩比得到适合的图像以进行更准确的诊断。
The medical images are very huge and different people have different demand for the transmission and quality of medical images. In this paper, authors compare JPEG＇s compression on DCT - based with JPEG2000＇s compression on DWT - based and make use of emulator MATLAB to contrast original image with compressed image in quality and size. Doctors earl select suited image according to different compress ratio to diagnose well and truly.
