A New Optimal Smoothing Filter for Edge Detection Based on the Energy Criterion
-
摘要: 本文提出一种基于能量准则的平滑滤波器,它可以用于滤除噪声、检测纹理结构和检测边 缘.和高斯函数的拉普拉斯算子相比较,这种平滑滤波器用于边缘检测时,具有更好的定位精 度以及同样的噪声抑制效果,对于各种图象所进行的实验,其结果是令人满意的.Abstract: Based on the energy criterion, a new optimal smoothing filter is proposed in this paper. Compared with the Laplacian-Gaussian filter, this filter is more precise for the location of edge and less sensitive to noise. Experiments have been performed on various images and the results are very satisfactory.
