Next, we can start to load the model by first specifying the path to our model. Leave your thoughts as comments below. The code itself is very much similar with our video object detection system. Since our model is in the same directory as our Python script, here I show you how to load the RetinaNet model. In my previous posts we learnt how to use classifiers to do Face Detection and how to create a dataset to train a and use it for Face Recognition, in this post we are will looking at how to do Object Recognition to recognize an object in an image ( for example a book), using SIFT/SURF Feature extractor and Flann based KNN matcher,. I would suggest you budget your time accordingly — it could take you anywhere from 40 to 60 minutes to read this tutorial in its entirety. Capturing the Video. As we all know that colors are made up of three primary colors: Red, Green, and Blue. In this video on OpenCV Python Tutorial For Beginners, I am going to show How to Detect Simple Geometric Shapes using OpenCV in Python.
