$1.(30)$ Create a binary image with initials of your first name and last name. For example, Nazrul Islam $$ NI$.$ Now generate a key of appropriate size and perform exclusive$-$OR encryption of your image. Then decrypt the image using the same key. Display the plaintext image, encryption key, ciphertext image and the decrypted image. $2.(30)$ Use the image $$mandi$.$tif$$ in Matlab and perform the following operations on it$.$ Extract the bit planes and then put them in reverse order to create a ciphertext image. Now from the ciphertext image, retrieve the plaintext image. Display the plaintext image, ciphertext image and the decrypted image. $3.(40)$ Take a color image and perform bit$-$plane exclusive$-$OR encryption. Then decrypt the original image. Display the plaintext image, ciphertext image and the decrypted image. PLEASE USE MATLAB AND SHOW CODE, screenshot of images as reference would be nice.
