Python(x,y) is now available in two versions: Full Edition (all Python packages are installed) and Basic Edition (with essential Python libraries only: PyQt4, NumPy, SciPy, IPython and matplotlib) SWIG 1.3.36 - SWIG is a compiler that integrates C and C++ with several languages including Python Mar 25, 2019 · OpenCV supports haar cascade based object detection.

Also on windows, You can use debug and release. In debug mode the detect multiscale return wrong output as to many rectangles out of image boundary.
