1. Load a color (RGB) image I, and display it. 2. Display the histograms of all three color channels of I. 3. Select a pixel location p in the image, and (a). display the 1111 square window Wp11,11 around pixel p (i.e., p is the reference point of this window) (b). show the RGB values of your image I at p (c). compute the intensity value [R(p)+G(p)+B(p)]/3 at p 4. Convert RGB image I to grayscale, display the histogram, and compute the mean and variance
