OpenCV and Python versions: This example will run on Python 2.7/Python 3.4+ and OpenCV 2.4.X/OpenCV 3.0+. This answer is good, but I feel your wording misrepresents the real performance characteristics: "even with this very small data set, the view method is substantially faster".In reality, the negation is O(n) and the argsort is O(n log n).This means the timing discrepancy will diminish for larger data sets - the O(n log n) term dominates, however your suggestion is an optimisation of the O(n) part. Refer to numpy.ndarray.transpose for full documentation. Ans: NumPy is an open source numerical Python library. (Faster) Non-Maximum Suppression in Python.
