Write a Matlab program which first performs high-pass filtering (you can use matlab func 'conv2' for this part) of an input gray scale image using the following filter: 0 1 0 A = 0.25 1 4 1 010 Scale the filtered image to range between 0 and 255. Then displays the filtered image using 3 pseudo colors, using the following color transformation: Color Red for values 0-80, Color Green for values 81-160, Color Blue for values 161-255. In matlab, you can use the function 'colormap' to change the colormap and use 'imshow' to display an image using a specified colormap. Comment on the visual effect, e.g. each color represents what attributes of the image?
