title: Blobs with OpenCV. Which library is best?
body: <p>I plan to start experimenting with blobs as a C++ user, with some experience at cv::Mat's from the OpenCV.</p>
  
  <p>Now the question is, which blobs library should I use if at all?</p>
  
  <p>I have seen these alternatives so far:</p>
  
  <ol>
  <li><a href="http://code.google.com/p/cvblob/" rel="nofollow noreferrer">cvBlobs (on google code)</a> -- that is a c library really, working with IplImage so it needs serious adaptation to c++.</li>
  <li><a href="http://opencv.willowgarage.com/wiki/cvBlobsLib#Code%20examples" rel="nofollow noreferrer">CvBlobsLib (on willowgarage opencv webpage)</a> -- that looks like a c++ library but has quite bad docs with plenty of stuff left unexplained and barely any code example.</li>
  <li>I have seen cv::findContours, cv::moments and cv::drawContours in the OpenCV 2.4.3 library.</li>
  </ol>
  
  <p>What do you suggest as an expert? My pressing issue: what will the new OpenCV not cover of cvBlobs on google code?</p>
