提出了一种新的图像去噪方法。所提出的方法采用多通处理的基础上，一个简单的分段线性滤波器，其行为是局部自适应的边缘检测算法。本文还提出了一种在噪声方差未知时自动参数整定的方法。计算机模拟和数码相机采集的图像实验表明，该方法对受高斯噪声污染的图像产生了非常满意的结果
A novel technique for image denoising is presented. The proposed approach adopts multipass processing based on a simple piecewise linear filter whose behavior is locally adapted by means of an edge detection algorithm. A method for an automatic parameter tuning when the noise variance is unknown is also presented. Computer simulations and experiments with pictures acquired by digital cameras show that the proposed approach yields very satisfactory results for images corrupted by Gaussian noise
