edge detection
Finding image contours
Edge detection is a technique in image processing that identifies boundaries where brightness or color changes sharply.
It's fundamental to computer vision, helping software locate objects, recognize faces, or read text by finding where one region ends and another begins.
Common algorithms include Sobel, Canny, and Laplacian filters: The edge detection picked up the outline of the car against the background.
