说明：  边缘检测是图形图像处理、计算机视觉和机器视觉中的一个基本工具，通常用于特征提取和特征检测，旨在检测一张数字图像中有明显变化的边缘或者不连续的区域，在一维空间中，类似的操作被称作步长检测（step detection）。(Edge detection is a basic tool in graphics and image processing, computer vision and machine vision. It is usually used for feature extraction and feature detection. It aims to detect the edge or discontinuous area with obvious changes in a digital image. In one-dimensional space, similar operations are called step detection)
