Sobel算子根据像素点上下、左右邻点灰度加权差，在边缘处达到极值这一现象检测边缘。对噪声具有平滑作用，提供较为精确的边缘方向信息，边缘定位精度不够高。当对精度要求不是很高时，是一种较为常用的边缘检测方法。本代码用sobel边缘检测，检查细胞边缘，有图。- 简体中文 繁体中文 英语 法语 德语 西班牙语
Sobel operator according to the pixel point up and down, left and right adjacent pixels gray weighted difference, at the edge of this phenomenon to detect the edge of the edge. The noise has a smooth effect, providing a more accurate edge direction information, edge positioning accuracy is not high enough. When the accuracy requirement is not very high, it is a kind of common edge detection method. The code with Sobel edge detection, check the cell edge, there is a fig.
