# wasm-face-detection
Face Detection using dlib/OpenCV in WebAssembly
[Try](https://seanchas116.github.io/wasm-face-detection/)
## Prerequisites
* cmake
* Install emscripten with [emsdk](https://github.com/emscripten-core/emsdk)
* Activate emscripten installation with `source /path/to/emsdk/emsdk_env.sh`
## Run
```
npm install
npm run configure:cpp
npm run build:cpp
npm run serve
```
## How to build OpenCV 4.2.0 for Emscripten (with contrib)
* `git clone [email protected]:opencv/opencv.git`
* `git clone [email protected]:opencv/opencv_contrib.git`
* `cd opencv`
* Edit `opencv/platforms/js/build_js.py`
```
