About OpenCV
OpenCV is the classic open-source computer vision library used for image processing and classical algorithms. It remains foundational but requires significant custom code for modern deep-learning pipelines, annotation, and managed deployment that Roboflow abstracts away.
What OpenCV does
OpenCV is the world's biggest computer vision library, open source under Apache 2 License with over 2500 algorithms since June 2000. It delivers a real-time optimized Computer Vision library with C++, Python and Java interfaces across Linux, MacOS, Windows, iOS and Android. The non-profit Open Source Vision Foundation operates it, also offering ML/AI model execution, courses and consulting via OpenCV.AI.
