Papers With Code is a free resource with all data licensed under CC-BY-SA. Today we’ll learn how to use OpenCV to do some simple object-detection with Twilio’s Programmable Video. This will allow you to add object detection to your video streams and open the pathway to many more image processing techniques using OpenCV! Let’s get started. Prerequisites So, to find an object of an unknown size in the image the scan procedure should be done several times at different scales.

Object detection and segmentation is the most important and challenging fundamental task of computer vision. It is a critical part in many applications such as image search, scene understanding, etc. However it is still an open problem due to the variety and complexity of object classes and backgrounds.
