(1) An improved Sobel operator with eight directions is proposed to extract a more accurate edge image; (2) To make the neighborhoods with similar structure obtain more weight, not only the Euclidean distance but also the edge image are considered when the similarity of neighborhoods is measured...
常用的边缘检测算法有Canny边缘检测算子、Sobel算 子、Prewitt算子、Robert算子,但是这些方法在很多方 面往往不尽如人意。另外,如何实现图像库中图像边 缘的自动提取已经成为一个日益重要的问题。 Marr边缘检测算法 [1] 克服了一般微分运算对噪 声敏感的缺点,利用能够反映人眼视觉特性的LOG算 ...
To improve the problem, we mainly use the Sobel edge detection to replace the Canny edge detection. Also, we make use of the Gaussian filter to filter noise. Finally, we improve the ellipse ROI size in tracking part and the performance of the FPS (frame per second) from 32 to 39. In...

The findings demonstrate that theedmABCmethod outperforms several standard edge detection techniques such asCanny,Prewitt, andSobel. Combining the ABC algorithm alongside grayscale values and statistical estimation has impacted the results significantly. Therefore, this study positionsedmABCas a promising ...
Gray edge gradients, for example, are prone to edge fractures and weak bounds in traditional ACM. The color gradient ACM has been improved to detect the proper cell edge, overcoming edge breakage and weak edge difficulties. The GVF model has the advantage of being insensitive to initialization,...
There are many edge detection algorithms have been developed for detecting the true edges from an image. These algorithms use different types of masks such as Robert, Prewitt, Sobel, Laplacian masks etc. Though the algorithms have some advantages and disadvantages, some of these perform better ...

11 that the edge extracted by the traditional Sobel has noise interference, and the edge extraction is fuzzy, the edge extracted by the improved Sobel operator is clearer, and the continuity of the edge is better. As shown in Fig. 12 that for a noisy image, after the traditional Sobel ...
