Normalizing an image in OpenCV Python. Fellow coders, in this tutorial we will normalize images using OpenCV’s “cv2.normalize ()” function in Python. Image Normalization is a process in which we change the range of pixel intensity values to make the image more familiar or normal to the senses, hence the term normalization.
