基于OPENCV的连通区域轮廓线标记代码，可以标记多个标签，自制定标签列表和图像数据区，非常方便，简单实用-OPENCV based connectivity contour marking area code, you can mark multiple labels, since the enactment of the label list and image data area, very convenient, simple and practical

摄像头摄取图像后，用两种常见的连通区域分析和标记的算法：1）Two- pass；2）Seed-Filling种子填充，并给出了两个算法的基于OpenCV的C++实现代码。-After the camera takes an image, analyze, and marked with two common regional connectivity algorithm: 1) Two-pass 2) Seed-Filling seed filling, and gives two algor
