2. Write a program called “unsharp” which is run as follows: – Ask the user for an image. – Open the image as a grayscale image. – Pad the image (you choose the padding method). – Perform unsharp masking on the given image using the spatial domain and a 3×3 averaging mask. – Remove the padding. – Save the result as a new image. – Display the original image and the resulting image. The program should assume that the images are 8-bit images, with grayscale values in the range of [0, 255]. Ensure t
