Given the image data "cruise.jpg", perform the following linear filtering:
a. Convert the image to gray scale and then create an 8-bit noisy image by adding Gaussian noise using the following code:

where I is the intensity image obtained from normalizing the gray scale image.
b. Process the noisy image using a Gaussian filter with the following parameters: convolution kernel size = 4, SIGMA = 0.8.
Compare the filtered image with the noisy image.
