基于小波灰度相似关联强噪声图像处理算法。通过对图像进行三层小波分解，得到各个方向上的分量。然后根据同一方向上各层之间的灰色关联度区分是噪声还是边缘。在对该点值进行增强或减弱。从而实现对强噪声图像的滤波。该算法比其他算法效果更明显。-Gray similarity based on wavelet image processing algorithms associated with strong noise. Three of the images by wavelet decomposition, by the weight of all directions. According to the same direction and then the gray correlation between the layers is the noise or the edge of distinction. Value at the point of increase or decrease. In order to achieve the image of strong noise filtering. This algorithm is more effective than the other algorithms.
