Description: 讨论和比较了几种常用的边缘检测算子。梯度
算子计算简单 ,但精度不高 ,只能检测出图象大致的轮廓 ,而对于比较细的边缘可能会忽略。Prewitt 和Sobel算子比 Roberts 效果要好一些。LOG 滤波器和 Canny算子的检测效果优于梯度算子 ,能够检测出图象较细的边缘部分。不同的系统 ,针对不同的环境条件和要求 ,选择合适的算子来对图象进行边缘检测。-Discussion and comparison of several commonly used edge detection operator. Gradient operator is simple, but accuracy is not high, only to detect the outline of the image generally, and for the more detailed the edge may be ignored. Prewitt and Sobel operator is better than Roberts effect. LOG filter and Canny operator detection better than gradient operator, can detect the edge of a smaller part of the image. Different systems for different environmental conditions and requirements, choose a suitable operator to image edge detection. Platform: |

Description: This paper presents a fuzzy topology-based method to facilitate the use of larger gradient kernels. The new method effectively limits the response area around the edge and prevents neighboring objects to affect each other. Synthetic images are used to show the superior noise suppression properties and response characteristics to both step and ramp edges. Natural images are also used to assess the performance of the newly proposed topological gradient estimation qualitatively. One of the fastest methods of localizing edges in images is based on small gradient kernels, such as Sobel, Prewitt, and Roberts. Although small gradient kernels provide a fast way Platform: |
