To find the coordinate of the eye corner using color differences, you'd typically analyze the contrast between the skin and the sclera (white of the eye) or the surrounding areas in a photo. Eye corners often appear as sharp points where color or brightness changes suddenly. This process is commonly used in computer vision or facial recognition. If you're interested in eye-related analysis like this, you might also want to explore tools like baby Eye Color Calculator, which uses genetic and visual data to predict or explore potential eye color outcomes — it's a fun and helpful way to learn more about eyes and how traits like color are passed down!
