摘要
在噪声图像中如何有效的提取边界是图像分析中的难点 ,常用的边界提取方法往往对噪声很敏感。文章针对这一情况采用了保持图像细节的多级组合滤波器先将噪声从图像中分离出来 ,然后再对图像进行边界提取。实验表明 ,该方法可以在有效的抑制噪声的同时提取出有意义的边界。
How to extract the edge effectively in noise image is a difficult problem in the field of image analysis. The traditional methods used to extract edge are often very sensitive to noise. In this paper, The noise is first removed by using Multistage Combination Filter remained the initial image's detail, after that ,the Extracting Edge will be completed. Experiments show that the method can extract edges effectively and suppress the noise at the same time.
