In this tutorial, we’ll learn about a step-by-step implementation and utilization of OpenCV’s Contour Approximation. When I first chanced upon the concept of Contour Approximation, the first question that hit me was: Why? Throughout my journey in Machine Learning and…

This is the final post in our three part series on shape detection and analysis. Previously, we learned how to: Compute the center of a contour Perform shape detection & identification Today we are going to perform both shape detection…

Last updated on July 7, 2021. 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…

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,…

I’m going to start this post by clueing you in on a piece of personal history that very few people know about me: as a kid in early high school, I used to spend nearly every single Saturday at the…

Quick question. How does a Pokedex work? Well, you simply point it a Pokemon, the Pokedex examines its physical characteristics, and the Pokemon is identified instantly. In this case, our smartphone camera is our “Pokedex”. We point our smartphone at…
