I am working on segmentation in 3d scenes and I was wondering if the KDTree algorithm in opencv provides the same clustering functionality as the one from PCL ? Can it region grow and can I add my own similarity functions ? Are there any other good region growing algorithms in opencv without manual initialization ?
