Hi,
Does anyone have a working trained model for this OpenCV implementation? I used the provided script to convert the model downloaded from https://github.com/pdollar/edges, but it seems that it does not work.
Thanks
The reason that the model from Pdollar github doesn't work is the sharpen parameter. You can try either setting the sharpen parameter to 0 and then retrain a new model based on BSDS or whatever data set you like or you can try correct the following lines in OPENCV structured_edge_detection.cpp source file:
int start = __rf.edgeBoundaries[currentNode * (__rf.edgeBoundaries.size() - 1) / (nTreesNodes * nTrees)]; int finish = __rf.edgeBoundaries[currentNode * (__rf.edgeBoundaries.size() - 1) / (nTreesNodes * nTrees) + 1];
(or you better keep the the multiple factor at a side variable such as: const int nBnds = (__rf.edgeBoundaries.size() - 1) / (nTreesNodes * nTrees)
Cheers, Ohad
Thanks, this one works great. I guess the reason why the model from https://github.com/pdollar/edges does not work is: they have updated their code according to the newer paper "Fast Edge Detection Using Structured Forests".
