2014-06-05 08:26:27 -0600 | asked a question | LINE-MOD/LINE-2D: Why does the OpenCV implementation use only silhouettes of the object? On his website (section "Software") Hinterstoisser notes that OpenCV implementation of LINE-MOD/LINE-2D uses only sihouettes when learning templates, but doesn't reason why. So here's my question: Why is that? The lines of code that I'm talking about can be found in file opencv/modules/objectdetect/src/linemod.cpp: For LINE-2D: And same for LINE-MOD: Why erode the mask? Why not just leave it what it is and take all the gradients anywhere on the object like Hinterstoisser et al. originally proposed in their paper? (As I understood it, LINE-MOD/LINE-2D is for detecting textureless object, not for detecting silhouttes of objects.) |
