摘要：The paper made a comparison test concerning wavelet-based image compressors- ECW 2.0, MrSID 1.4 and EYACODER. The 12 kinds of test data were built according to the given target compression rates, which are 2, 3, 5, 6, 8, 10, 15, 20, 25, 30, 50 , to compare above mentioned three wavelet compressors in term of compression speed, compression rate, and reconstructed image quality. The method of PSNR (peak signal noise rate) in the paper was taken to evaluate the compressors by comparing the difference between the reconstructed and original pixel value. The test result shows EYACODER and MrSID1.4 are better than ECW 2.0 in doing image compression when the target compression rate is less than 3, and the tendency in viewing is getting neutral when the given compression rate is getting larger
