With over two million downloads per week, OpenCV is the most popular open source computer vision library in the world. It implements over 2500 optimized algorithms, works on all major operating systems, is available in multiple languages and is free for commercial use. This talk will primarily provide a technical update on OpenCV: What’s new in OpenCV 4.0? What is the Graph API? Why are we so excited about the Deep Neural Network (DNN) module in OpenCV? (Short answer: It is one of the fastest inference engines on the CPU.) We will also share plans for the future of OpenCV, including new algorithms that we plan to add through the Google Summer of Code this year. We will also briefly share info on the new Open Source Vision Foundation (OSVF), and on OpenCV’s sister organizations, CARLA and Open3D, and some of the initiatives planned by these organizations.
