I'm currently using OpenCV 3.0.0 connectedComponents() and connectedComponentsWithStats() functions.

I have been trying to access the statsv(label, COLUMN) with no luck.

I need to access the connected components' statistics (left, top, area, etc.) and the documentation does not really help much!

Thank you Marco for your concern. – Ahmad Al-Hourani Feb 14 '16 at 17:13
Thank you beaker, opencv documentation was misleading when stating how statsv matrix is accessed. "Statistics are accessed via statsv(label, COLUMN)".. it is instead accessed via statsv.at(label, COLUMN)!! – Ahmad Al-Hourani Feb 14 '16 at 17:35
