Very frequently, the image is a "black-and-white" image: in … WebIn LineRider we introduce the basic concepts of image processing. Your robot has a simple 1D camera composed of just 32 pixels. We will learn how to write code which reads the image and determines where a white line is located on the image. We will develop a feedback algorithm so your robot follows the line to complete a course. simply chiropractic york
