## What it is
A repository of prebuilt OpenCV binaries (32-bit and 64-bit) compiled with MinGW on Windows, covering versions from 3.3.1 through 4.5.5 including contrib modules. It saves Windows developers using MinGW-based toolchains (Code::Blocks, Qt, CMake) from having to compile OpenCV themselves.

## Use cases
- use opencv with mingw on windows without building from source
- download prebuilt opencv dlls for codeblocks
- set up opencv for a qt project on windows
- link opencv 4.5 with contrib modules in a mingw-w64 project
- avoid cmake compilation of opencv on windows
- get 32-bit and 64-bit opencv builds for windows

## When to choose
- you develop C++ on Windows with MinGW/Code::Blocks/Qt and need ready-to-use OpenCV binaries
- you want opencv-contrib modules included without compiling
- you need an older OpenCV version (3.x/4.x) as a MinGW build

## When to avoid
- you use MSVC (Visual Studio) - official OpenCV Windows binaries are a better fit
- you need the latest OpenCV release or active updates - the last build is from 2022
- you target Linux or macOS
- you need a licensed/supported distribution - no license file is provided here

## Facets
- artifact type: library
- maturity: maintenance
- function: computer-vision, image-processing, machine-learning
- domain: computer-vision, image-processing, machine-learning, developer-tools
- platform: windows, cpp
- tags: opencv, mingw, prebuilt-binaries, cmake, dll, opencv-contrib, codeblocks, qt
