Convert numpy array to image opencv from www.digitalwaze.com

Np.uint32 data type is not supported by opencv (it supports uint8, int8, uint16, int16, int32, float32, float64) cv.cvtcolor can't handle numpy arrays so both arguments has to be converted to opencv type. Clone the repository, go to the projec folder then: You need to convert the python ndarray <=> c++ cv::mat.
