问题描述
我需要在一个C ++应用程序使用的图像上。我可以实现我自己，但我试图使用Boost的 wiki文章中提到的/不相交的集合实施。
I need to use the connected component labeling algorithm on an image in a C++ application. I can implement that myself, but I was trying to use Boost's union-find/disjoint sets implementation since it was mentioned in the union-find wiki article.
我无法弄清楚如何创建disjoint_sets对象，以便它会和我有（无符号短）的图像数据。我在想什么？ Boost的文档中的例子并不作任何意义，我。我需要所有的额外图表中那些例子天书时，我有一个形象？或者，有没有已经是OpenCV的连接成分标签的实现。目前，我们正在使用的OpenCV 1.1 pre1和Boost 1.37。
I can't figure out how to create the disjoint_sets object so that it'll work with the image data I have (unsigned shorts). What am I missing? The examples in the Boost documentation aren't making any sense to me. Do I need all the extra Graph mumbo-jumbo in those examples when I have an image? OR, is there already an OpenCV connected component labeling implementation. Currently we're using OpenCV 1.1pre1 and Boost 1.37.
推荐答案
奇怪的是，在OpenCV中没有CCL。但是，是在参考手册中描述的解决方法。见为cvDrawContours 的例子。当我试图使用它，我对第一个和最后一个行和图像列一些奇怪的行为，但我可能做错了什么。
Surprisingly, there is no CCL in OpenCV. However, there is a workaround that is described in the reference manual. See the example for cvDrawContours. When I tried to use it, I had some strange behaviour on first and last rows and columns of an image, but I probably did something wrong.
的另一种方法是使用的库
An alternative way is to use cvBlobs library.
