摘要: 与传统的傅里叶变换去噪相比,小波能去噪同时保留图像细节特征。针对较好的小波去噪,本文研究了小波阈值去噪的阈值函数选取,阈值大小确定和小波去噪方法。

关键词: 小波 图像去噪 阈值

Abstract: Compareed with traditional Fourier-transform denoising, wavelet denoising can make the image denoising and keep the detail of the image. This paper is mainly about choosing of the thresholding function, ascertaining of the threshold and wavelet denosing.

Key words: Wavelet,Image denoising,Threshold
