Contour detection with digital image processing

Abstract

This article provides an overview of contour detection using digital image processing. It describes in detail the digital image processing and its advantages, as well as its application in a specific field. In this article, we use the Python language, and for the sake of efficiency, we also present the necessary packages. Next, we will present a method for the detection of edges and circles, which requires the application of the Hough transform. We also look at the thinning process, which helps to achieve a more accurate result. Then, with the help of the acquired knowledge, the detection of the contours will be demonstrated with the help of an example program. At the end of the article, we also briefly discuss the calculation of shape characteristics.
