![]() Associate an intensity value to each of the 95 printable ASCII characters.I hope you agree in that a good way to do this mapping is to: It is obvious then that the inputs of the mapping will be intensity values and the outputs ASCII characters. Since what defines the grey level of a pixel in a grayscale image is its intensity value, we have to find a way that allows us to relate or match ASCII characters and intensity values. Execution flow of the program as explained in part 1. This is what, without further ado, we will discuss below. What we have to implement now is the mapping from the grayscale version of the input image to the ASCII art image. We already have a grayscale version of the image we want to convert and we have also developed a method that allows the user to adjust the contrast of the image.
