摘要: 提出一种将小波变换去噪和高阶统计量滤波法去噪相结合用于图像去噪的新方法, 既较好地保持了图像边缘细节, 又有效地虑除了噪声. 实验结果表明, 相对于单一的小波变换去噪或高阶统计量滤波法去噪, 所给方法在视觉和峰值信噪比增益上都取得较好效果.

关键词: 图像去噪, 小波变换, 高阶统计量

Abstract: we proposed a new method of the combination of wavelet transformation denoising with High Order Statistics (HOS) filtering method to denose images, this method deals with both preserving edge details and smoothing n oise better. Simulation experimental results indicate that the method gives better visual quality and PSNR gains than applied wavelet transformation denoising method or HOS filter only.

Key words: image denoising, wavelet transformation, higher order statistics 
