GoCV

Lets programs written in Go use OpenCV for computer vision, like detecting faces in webcam video.

New this week

What it does

GoCV connects the Go programming language to OpenCV, a widely used library for computer vision, the field of teaching computers to understand images and video.

With it, Go programs can read from cameras, process images, detect faces and objects, stream video and run AI models for vision tasks. The README includes small examples, such as drawing boxes around faces seen by a webcam.

It works on Linux, macOS, Windows and Docker, and can use NVIDIA graphics cards or Intel's OpenVINO toolkit to run faster.

Who it's for

Go developers adding image or video analysis to their programs.

Can I use it without coding?
