## What it is
Native Node.js bindings for the OpenCV computer vision library, exposing Matrices, image reading/writing, and cascades like face detection to JavaScript. It enables real-time vision tasks such as webcam face detection and video stream annotation from Node.

## Use cases
- detect faces in images from node.js
- annotate video streams with computer vision
- read and process images in javascript
- control quadcopters with vision from node
- pipe image files into opencv matrices

## When to choose
- you need OpenCV functionality from Node.js with native performance
- you want simple face detection or image manipulation in JavaScript

## When to avoid
- you need modern OpenCV 4.x features or active maintenance
- you are not tied to Node.js and can use Python or C++ directly

## Facets
- artifact type: library
- maturity: maintenance
- function: computer-vision, image-processing
- domain: computer-vision, image-processing
- platform: windows
- tags: opencv-bindings, native-addon, face-detection, streams, nodejs, linux, macos
