Will Blob Analysis be a built-in feature of OpenCV?

Actually only some Blob Analysis libraries for OpenCV exists (cvBlob, cvBlobsLib and BlobLib) and even if they are working fine, they seem to be outdated by now and they do not support the new OpenCV structures like Mat. Even if it is possible to use findContours() to identify connected components, you still need external libraries for computing basic blob measures, like centroid, bounding box, axes, eccentricity, etc...

Is there any effort planned to embed these functionalities into the core OpenCV functions?

Many thanks!

This would indeed be a good adition to the openCV library.

Blob analysis should be native to OpenCV instead of an add-on library. Thanks zerog80 for raising the question.

OpenCV does lack some features in the blob analysis field

There are some patches available by Jason Newton which support the Mat structures and has some basic measures. Link..
