Unlike C++-OPENCV, Python-opencv doesn ' t has a function like convertTo. But we can modify image data types using Numpy.

For example, we have a image with image depth Cv2. CV_64FC1 and we want to the change of the depth to CV2. Cv_8uc1

Import NumPy as Npmax_pixel=np.amax (original_img) img=original_img/max_pixel*255img=img.astype (np.uint8)

Since an image is processed as a array, many functions in OpenCV also has their equivalents in Numpy. And PYTHON-OPENCV are more powerful with the help of Numpy
