a. Task 2: Write a Matlab code to read 'rice.png' image and to do the following: Add salt and pepper noise into the rice image (imgl) of amount 0.05 and save it in a noisy_img. b. Apply a 5 x 5 average filter with replicate border into the noisy_img, and display the result. Apply a 3 x 3 median filter into the noisy_img, and display the result. d. Apply a Gaussian low-pass filter on the noisy_img with Do=36 and D0=18 and display the results C
