opencv
OpenCV is an open-source library containing hundreds of computerized vision algorithms, and it mainly offers C++ API, with Python bindings as well. Its modular structure includes modules such as image processing (imgproc), video analysis, object detection (objdetect), camera calibration, deep neural network (dnn), and panorama splicing (stitching).

- You can analyze visual data using image processing algorithms.
- You can perform object detection and classification operations in computer vision projects.
- With the dnn module you run deep neural network models, with the video module you make motion prediction and object tracking.

OpenCV 5 Is Here: The Biggest Leap in Years for Computer Vision
“There is a CLI photogrammetry OSS project with rather litigious faculty members behind the code. However, at least that group was upfront about what was expected of the library users, and didn't do something dodgy like quietly merge it into another community library like OpenCV.…”

OpenCV 5 Is Here: The Biggest Leap in Years for Computer Vision
“Image augmentations library Albumentations is heavily based on OpenCV, which allows it to beat torchvision, Kornia, PIL, and other similar libraries. But there is still a huge room for improvement in terms of performance, as for some low level operations StringZilla or Numkong…”
