OpenCV shape detection

This tutorial is the second post in our three part series on shape detection and analysis. Last week we learned how to compute the center of a contour using OpenCV. Today, we are going to leverage contour properties to actually label and identify shapes in an image, just like in the figure at the top of this post. […]

OpenCV center of contour

Today, we are going to start a new 3-part series of tutorials on shape detection and analysis. Throughout this series, we’ll learn how to: Compute the center of a contour/shape region. Recognize various shapes, such as circles, squares, rectangles, triangles, and pentagons using only contour properties. Label the color of a shape. While today’s post is […]
