基于多尺度和多结构元的形态边缘检测

Morphological Edge Detection Based on Multi-scale and Multi-structuring Elements

图像的边缘检测是图像处理中的基本 ,并且又十分重要的内容 ,它是图像分割、模式识别和计算机视觉的基础 .当前存在许多边缘检测的方法 ,如Robert算子、Sobel算子、Laplaccian算子等 ,但是这些算子大都基于邻域平均的方法 ,使得处理后的图像边缘模糊 ,影响人的视觉 .提出了一种基于多尺度多结构元的形态边缘检测算法 ,并通过试验证明文中算法的有效性 ,也得到了比较好的效果 ,得到了比较清晰的 。

Edge detection is the important content in the image processing,and it is the basis of image segmentation,pattern recognition and computer version.Currently there are a lot of methods such as Robert function, Sobel function,and Laplaccian function.But all these algorithms are based on the average of neighborhoods.So after processing,the edge of image is dim, and the image affects our version.The morphological edge detection algorithms based on multi-scale and multi-structuring elements are offered, which has been proved valid and effective.
