Sobel edge detectionGradient algorithmImage edgeAnti-noise performanceThe paper proposes an improved gradient algorithm which is based on the existing sobel edge detection. The algorithm is not only simple, but also can solve the coordination problem between the detection precision and anti-noise ...

First of all, first section of this article to the traditional edge detection algorithm (Roberts, and Prewitt operators, and operator, Sobel operator Krisch, and Canny operator operator, the Gauss-Laplace operator) General steps for testing, template provides an analysis and comparison of algorithms...
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 ...
(Edge-detection) Edge detection of median-filtered image using Sobel operator (modified algorithm proposed in Abbiramy and Shanthi (2010)5) followed by morphological enhancements (dilation, closing, and erosion). 5. (GMM) Motion detection algorithm using Mixture of Gaussian Model (GMM) with the...
Consequently, this chapter included a comparative study on the shape and size of the edge detection filter that was used during the calculations of the indeterminacy (uncertainty) neutrosophic subset I in the NS. Different filters, namely the Sobel filter, the Prewitt filter, and the unsharp ...
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 ...
