Template Matching for Object Detection with OpenCV and Python

Template Matching for Object Detection with OpenCV and Python

March 27 2023 Yacine Rouizi
OpenCV Image Processing Python Computer Vision

In this tutorial, we will learn how to use OpenCV to perform template matching. Template matching is a simple form of object detection that is computationally inexpensive. It involves finding areas of an image that are similar to a patch (template).
