Opencv 3 normalize. How to normalize images in PyTorch ?

Parameters a input array. Calculates the per-element difference between two arrays or array and a scalar. If the array is a single column or a single row, the function performs a 1D transform. To achieve this, we will first use the Cv2 imshow to display an image, after which we will use the normalize function and compare the 2 images to spot the difference. The function cv::completeSymm copies the lower or the upper half of a square matrix to its another half. OpenCV program in python to demonstrate normalize function to read an image using imread function and then normalize the given image normalize function and then display the resulting image as the output on the screen:.
