| 摘 要： | 利用2D小波变换对含噪图像进行消噪处理。基于小波变换具有的多分辨率特点，分析图像信号的局部特征，滤除掉含噪图像中的高频成份，达到降低噪声的目的。文中给出了含噪二维图像信号模型，以及利用2D小波分析对图像信号消噪的步骤。同时介绍了MATLAB6．5中小波分析支持的图像格式。经噪声图像仿真测试，小波变换中独立阈值法具有较好的消噪效果。

| Abstract: | In order to eliminate noise of image, the 2D wavelet transform algorithm is presented. The wavelet transform has the multi-resolution ability. By analyzing the part characteristic of the image with noise and filtering the high-frequency part, the noise is reduced from image. The model of 2D image signal with noise and the steps of denoising using the 2D wavelet transform are proposed. At the same time, the style of image supported by the wavelet transform toolbox of MATLAB6.5 is described. According to the ... |
