基于Sobel算子的图像边缘检测 索贝尔算子(Sobeloperator)主要用于获得数字图像的一阶梯度,是一种离散性差分算子。它是prewitt算子的改进形式,改进之处在于sobel算子认为,邻域的像素对当前像素产生的影响不是等价的,所以距离不同的像素具有不同的权值,对算子结果产生的影响也不同。一般来说,距离越远,产生的影响越小。 ...
Abstract:Edge detection is one of the basic problems in image processing and computer vision, and the Sobel operator is one of the most important operators for edge detection. In view of the limitations of the traditional Sobel operator and the low efficiency of serialized image processing on the...

Abstract: Aiming at the shortcomings of traditional Sobel edge detection algorithm such as noise sensitivity and inaccurate location, an improved Sobel operator edge detection algorithm is proposed. Based on mean calculation and difference processing, a 5×5 gradient weight template is constructed. The ...
However, the accuracy of traditional edge detection methods in edge extraction is low. For the actual image, the grey edge is sometimes not very clear, the image also contains noise. The detection result of the traditional Sobel operator is relatively accurate, but the detection result is rough...
