Quick jump is to determine the suspicious area of the traffic light by detecting the color of the traffic light. You can choose the (5x, 5y) method, that is, the fast jump positioning is performed in units of 5 pixels, and the image information is read to quickly pre-position the suspicious area of the traffic light , In order to achieve the purpose of reducing processing image information and speeding up processing speed. Among them, traffic light colors include red, yellow, green and black.
[0029] S3: Divide the area of the preliminary position of the traffic light obt
