## What it is
Go bindings for the OpenCV computer vision library, exposing the OpenCV 1.x C API via CGO and an experimental OpenCV 2.x C++ API (the gocv subpackage) via SWIG. It allows Go programs to perform image and video processing by linking against a native OpenCV installation on Linux, macOS, or Windows.

## Use cases
- use opencv from go
- process images in golang
- face detection in a go program
- read video frames with go
- go bindings for opencv 2 c++ api
- computer vision library for go
- convert cv::Mat to a go matrix

## When to choose
- You need to call the legacy OpenCV 1.x C API from Go through CGO
- You are maintaining an existing codebase already built on this binding
- You want to experiment with partial OpenCV 2 API access via the SWIG-based gocv subpackage

## When to avoid
- You want an actively maintained, well-documented Go OpenCV binding - hybridgroup/gocv is the modern standard
- You need comprehensive OpenCV 2+ or OpenCV 4 coverage, since the gocv wrapper here is incomplete and under-documented
- You want cross-platform builds without manually installing and configuring native OpenCV and MinGW

## Facets
- artifact type: library
