Blob与OpenCV。哪个库最好？ [英] Blobs with OpenCV. Which library is best?

问题描述

我计划开始用blob作为C ++用户进行实验，在cv :: Mat从OpenCV。的经验。

现在的问题是，哪个blobs库

li> cvBlobs（在Google代码上） - 这是真正的ac库，与IplImage一起工作它需要严重适应c ++。

CvBlobsLib（on willowgarage opencv网页） - 看起来像一个c ++库，但有相当不良的文档，大量的东西没有解释，几乎没有任何代码示例。

我看到cv ::

你建议作为一个专家怎么样？你可以在OpenCV 2.4.3库中找到findContours，cv :: moments和cv :: drawContours我的紧迫问题：新的OpenCV在google代码上没有覆盖cvBlobs？

关于这个问题的问题，我在这里问问 SimpleBlobDetector 。您可能感兴趣。

解决方案

您应该使用 SimpleBlobDetector 类。你几乎创建一个类型 SimpleBlobDetector 的对象，然后调用 detect（cv :: Mat input，vector< cv :: KeyPoint> keypoints，cv :: Mat mask）函数，使用cv :: Mat图像作为输入，一个空矢量用于关键点，另一个cv :: Mat作为图像特定区域的可选掩码，以查找关键点in。

请注意，cv :: Mat对象已经接管了OpenCV早期版本中所有以前单独的图像和矩阵类的图像和矩阵存储任务。

I plan to start experimenting with blobs as a C++ user, with some experience at cv::Mat's from the OpenCV.

Now the question is, which blobs library should I use if at all?

I have seen these alternatives so far:

1. cvBlobs (on google code) -- that is a c library really, working with IplImage so it needs serious adaptation to c++.
2. CvBlobsLib (on willowgarage opencv webpage) -- that looks like a c++ library but has quite bad docs with plenty of stuff left unexplained and barely any code example.
3. I have seen cv::findContours, cv::moments and cv::drawContours in the OpenCV 2.4.3 library.

What do you suggest as an expert? My pressing issue: what will the new OpenCV not cover of cvBlobs on google code?

Here is the link for the follow-up question on this subject, where I ask about SimpleBlobDetector. You might be interested.

解决方案

You should use the SimpleBlobDetector class in OpenCV 2.4. You pretty much create an object of type SimpleBlobDetector and then call the detect(cv::Mat input, vector<cv::KeyPoint> keypoints, cv::Mat mask) function with a cv::Mat image as input, an empty vector for keypoints, and another cv::Mat as an optional mask for a specific area of the image to look for keypoints in.

Note that the cv::Mat object has taken over image and matrix storage duty for all of the formerly separate image and matrix classes in the earlier releases of OpenCV.
