Write a program in Python using the OpenCV library that: A) Gets the name of an image from the command line and reads the image. B) Obtains the gradient in the x direction using the Sobel operator and converts it to an uint8 image. C) Obtains the y-direction gradient using the Sobel operator and converts it to an uint8 image. D) Blends the above two images using the same weight. E) Displays the original image and images of sections (b), (c) and (d) in a 2-in-2 window.
