A simple way to maximize the contrast between pixels is to change the red, green and blue components
of each pixel to their minimum or maximum values. If a component's value is between 0 and 127, the
component is changed to 0. If a component's value is between 128 and 255, the component is changed
to 255. Use the new component values to create the pixel's new colour.
• How many different colours could there be in an image that has been created by this filter? Be
prepared to explain your answer to a TA.
Develop a filter named extreme_contrast that returns a copy of an image in which the contrast
between the pixels has been maximized.
