摘要
本文基于Haar小波多分辨分析研究非线性图像消噪 ,通过小波收缩得到消噪的阈值范围 ,提出了小波包的重构 .实验结果表明 :Harr小波图像处理 ,实现再次低通滤波图像的噪声消除 ,其高频滤波特性优良 。
In this paper, research of nonlinear image noise removal is based on Haar wavelets multiresolution analysis. We obtain thresholding bounds of image noise removal through wavelet shrinkage. The reconstruction of wave packets is reached. A better image noise removal is obtained by our experimental results as dual-low pass filter.
