基于小波阈值的图像去噪方法研究

Research on Wavelet Image Threshold Denoising

本文概述了小波阈值去噪的基本原理,对常用的几种阈值去噪方法进行了分析比较和仿真实现。最后结合理论分析和实验结果,讨论了一个完整去噪算法中影响去噪性能的各种因素。为实际的图像处理中,小波阈值去噪法的选择和改进提供了数据参考和依据。

This paper has outlined the theory of wavelet threshold denoising , then done comparing experiments using several good threshold denoising methods. Finally according to the theory analysis and simulation results, the paper discusses several kinds of factors which affect the denosing capability in a complete denoising algorithm. That provides the date reference of threshold denoising methods in actual image process.
