If processing techniques make use of operators defined in the real plane, an approximation problem arises. Very frequently, the image is a "black-and-white" image: in this case, one is usually interested in obtaining a smooth approximation of the boundary between "inside" and "outside."

In this context, we are interested in digital curves extracted from contours of objects contained in digital images. In particular, we propose a fully discrete structure, based on the notion

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. porterhouse in cast iron skilletWebJan 8, 2013 · Contours can be explained simply as a curve joining all the continuous points (along the boundary), having same color or intensity.
