OpenCV 连通区域标记 在图像处理和计算机视觉中,连通区域标记(Connected Component Labeling, CCL)是一个非常重要的技术。它的任务是识别图像中所有独立的连通区域,并为每个区域分配一个唯一的标签。在本文中,我们将介绍如何使用 Python 和 OpenCV 库进行连通区域标记,并提供相关代码示例。 什么是连通区域标记? 连通区域...
连接组件标记算法(connected component labeling algorithm)是图像分析中最常用的算法之一,算法的实质是扫描二值图像的每个像素点,对于像素值相同的而且相互连通分为相同的组(group),最终得到图像中所有的像素连通组件。扫描的方式可以是从上到下,从左到右。对于一幅有N个像素的图像来说,最大连通组件个数为N/2。扫描...

OpenCV-Python执行速度远低于C++，揭秘原因 联通组件标记算法（Connected Component Labeling Algorithm）是图像分析中的一项关键技术。该算法的核心思想是遍历图像中的每个像素，将像素值相同的区域划分为同一组，从而得到图像中所有连通组件的信息。在OpenCV库中，提供了两个相关的函数：cv::connectedComponents和cv::connecte...
