Selective Search implementation in OpenCV gives thousands of region proposals arranged in decreasing order of objectness. For clarity, we are sharing results with top 200-250 boxes drawn over the image. In general 1000-1200 proposals are good enough to get all the correct region proposals.

WebbNearestNeighbors implements unsupervised nearest neighbors learning. It acts as a uniform interface to three different nearest neighbors algorithms: BallTree, KDTree, and a brute-force algorithm based on routines in sklearn.metrics.pairwise . The choice of neighbors search algorithm is controlled through the keyword 'algorithm', which must be ...
