OpenLvVision OpenCV

OpenLvVision OpenCV is a powerful LabVIEW wrapper for the OpenCV library. As an independent, community driven project (not officially affiliated with OpenCV), it brings advanced computer vision algorithms and capabilities directly into LabVIEW, utilizing efficient Mat handling and polymorphic VIs.

📘 Documentation: For a complete reference of all functions and detailed usage, visit openlvvision.org/docs/opencv/
This library is currently in active development. Additional OpenCV modules will be included in future updates.

🔌 Dynamic MAT API

The Mat type is reconstructed as closely as possible using malleable and polymorphic VIs. If a function can be done in OpenCV C++, there is a high chance it will also work in the LabVIEW version.
