| 摘 要： | 图像去噪是图像预处理中一项重要环节.针对线性小波分析在图像去噪中会丢失一些细节信息这一缺点,利用数学形态学算子的非线性特征,构建了一种非线性的可用于灰度图像处理的形态中值小波,并应用于图像去噪.对比实验结果表明,该方法比线性小波去噪方法具有更好的去噪性能,图像细节信息损失更小.

| Abstract: | Image denoising is one of the most important steps in image pretreatment.Aiming at the disadvantage of information loss in detailed image by the linear wavelet denoising,a nonlinear morphological median wavelet for gray image processing based on nonlinear character of mathematical morphological operator is constructed.This morphological median wavelet is applied to image denoising. Experimental results show that the morphological median wavelet is of better denoising performance and less information loss in detailed image. |
