Multidimensional arrays are used in image processing in C++. A gray-scale image of size m*n is represented as a m*n matrix (array). Each pixel can be shown using a double number between 0 and 1 (0 for black and 1 for white and numbers between 0 and 1 for the gray values).

Question

Multidimensional arrays are used in image processing in C++. A gray-scale image of size m*n is represented as a m*n matrix (array). Each pixel can be shown using a double number between 0 and 1 (0 for black and 1 for white and numbers between 0 and 1 for the gray values). Let's say we scan a document and notice that we have a dark background. Can you think of a function that gets an image as a 2D array and eliminates its background? What operations are needed to make an image lighter? How about sharpening or softening? Now with this definition, what do you think of software like Photoshop? How can we write a small version of Photoshop that only works on gray images and does sharpening and softening?
