It has more than 2,500 optimised algorithms, a comprehensive mix of both classic and state-of-the-art computer vision and machine learning methods. These can be used to detect and recognise faces, identify objects, classify human actions in video, track camera and object motion, extract 3D models, stitch images together to produce high-resolution panoramas, and much more. The library has interfaces for C++, Python, Java, and JavaScript, runs on Windows, Linux, macOS, Android, and iOS, and accelerates work on CPU (SIMD), CUDA, OpenCL, and Vulkan.\nOpenCV 5.0 is a major release built on OpenCV 4.x. C++17 is now the minimum required standard, Python 2 support has been dropped (Python 3.6+ is required), and the legacy C API has been fully removed. New data types (CV_16BF, CV_32U, CV_64U, CV_64S, CV_Bool) and proper 0D/1D array support extend the core, while the former calib3d module is split into the geometry, calib, stereo, and ptcloud modules. A next-generation DNN engine now covers over 80% of the ONNX specification (up from under 23%), with ONNX Runtime integration and models hosted on Hugging Face. Performance gains include Universal Intrinsics 2.0 (SSE/AVX/NEON/SVE/RISC-V), Vulkan compute support, image-warping speed-ups of 10% to over 300%, and USAC as the default framework for robust estimation.\n## Introduction[#](https://docs.opencv.org/5.0/#introduction \"Link to this heading\")\n * [Introduction](https://docs.opencv.org/5.0/intro.html)\n\n\n## How to use pre-built OpenCV
