OSS TanbouOverview
OpenCV is an open-source library for image processing and computer vision. Centered on C++, it provides modules for image I/O, feature extraction, object detection, DNNs, video, camera calibration, and stitching.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Assemble vision pipelines from purpose-specific modules
Its module tree separates core operations, image codecs and processing, features, object detection, DNNs, video I/O, calibration, stitching, and machine learning. It also contains binding-related modules for Python, Java, JavaScript, and Objective-C.

From image-analysis prototypes to embedded processing pipelines
It fits applications that combine established algorithms and I/O for cameras, video, or still images. Fix the target device, resolution, latency, accuracy requirements, and language binding, then benchmark representative data.

Align core, contrib, and target versions
Additional functionality lives in the separate opencv_contrib repository. Keep the binding, core and contrib versions, OS binaries, and hardware backend compatible, and check the documentation for the chosen release before relying on an API. GitHub currently identifies the repository as Apache-2.0.
