OpenCV is the foundation library of computer vision: image/video processing, geometry, and classical algorithms that still wrap every deep-learning vision system, preprocessing, camera handling, and post-processing on a million deployed edge devices.
Pricing: Free and open-source (Apache 2.0).
No: cameras still need capture, calibration, cropping, and post-processing, and many edge tasks (motion, measurement) remain classical. OpenCV is the plumbing; models are the brains.
Before and after the model: frame acquisition, preprocessing, geometric ops, then drawing/measuring/tracking on outputs, plus pure-classical pipelines where DL is overkill.
