% Exercise 12 (Noise reduction using averaging) Load the grayscale image, cameraman.tif. Generate four new images with salt-and-pepper noise added to the original image. Take the average of these four, and check if averaging reduced the noise. Repeat the experiment using 10 and 20 noisy images and observe the results.

(Note: Convert image data from uint8 to double before applying any arithmetic operations.) (Note: You can calculate the average in a loop. Average of A and B is A/2+B/2; Average of A, B, C is A/3+B/3+C/3; and )
