The objective of this mini-lab is to learn how to use the if-else construct by selectively changing the colors of pixels in an image.
colorSwitchthat will replace one color in an image with another. For example, you might want to replace all of the blue pixels in an image with black. Your function should take three parameters: the picture, the color that will be replaced, and the color that will replace it. It should return the modified picture. (Your function should not change the picture that is passed in as a parameter, the first step in your function will be to make a duplicate.)
Tip: This function is very similar to the
removeRedEyefunction in the notes. The only differences are that this function works on the entire image, and the color that will be changed is also passed in as a parameter.
Analysis Question: Could your new function be used for red-eye removal? If not, what changes would be necessary?
