OpenCV is an open‑source computer vision and machine learning library written in C++. It provides over 2,500 optimized algorithms for image and video analysis, object detection, and deep‑learning inference.

Use cases

• detect faces and objects in photos or video streams
• perform real‑time video stabilization and stitching for panoramas
• extract 3D models from stereo camera data
• run deep‑learning models (ONNX, TensorFlow) on images using the DNN module
• preprocess images for OCR or medical imaging pipelines
• track motion and gestures for AR/VR applications

When to choose

• You need a mature, widely‑used library with extensive algorithm coverage.
• Your project requires cross‑platform support (desktop, mobile, embedded).
• You want hardware acceleration (CUDA, OpenCL, Vulkan) for high performance.
• You need both classic CV methods and modern deep‑learning inference in one package.

When to avoid

• You are looking for a pure Python solution with minimal native dependencies.
• Your application demands a small footprint or zero‑C++ runtime.
• You need a specialized domain‑specific library (e.g., medical imaging DICOM handling) that OpenCV does not provide out of the box.
