GoCV gives programmers who use the Go programming language access to the OpenCV 4 computer vision library.

The GoCV package supports the latest releases of Go and OpenCV v4.5.1 on Linux, macOS, and Windows. Our mission is to make the Go language a “first-class” client compatible with the latest developments in the OpenCV ecosystem.

GoCV also supports the Intel OpenVINO toolkit.
