摘要
提出了一种先去噪再利用小波变换的图像压缩方法,用Matlab软件编程实现算法。实验仿真结果显示,图像在具有高压缩比的同时,重构图像的质量也较优;使用不同的小波基函数,效果不同。
Tiffs paper discusses an algorithm based on wavelet transformation, which is realized by programming in Matlab. The .riginal image is de-noised by using the functions of wavelet toolbox at first. The simulation results show that the algorithm has excellent effects in the image reconstruction, and the study shows valuable in image compression.
