On the grid below, draw a simple apple using only 3 colors: RED = (255, 0, 0) GREEN = (0, 255, 0) YELLOW = (255, 255, 0) Draw a 4x4 apple. Then write the 3 numbers for each colored cell. This is exactly how a computer stores a picture: as a grid of numbers.

Your phone camera stores every photo exactly like this — a giant grid of [R,G,B] numbers. A 12-megapixel photo = 12 million sets of 3 numbers!

Every photo on your phone is a giant grid of numbers. A 12-megapixel image is a matrix with 12 million RGB triples. Computers do not see colors. They read numbers. That is the first step of image recognition.
