Facedetect

Facedetect is used for face detection in image. It provides a simple interface. At the same time, you can use your own model.

Usage

import { FaceDetector } from '@paddlejs-models/facedetect';

const faceDetector = new FaceDetector();
await faceDetector.init();
// Required parameter：imgEle(HTMLImageElement)
// Optional parameter: shrink, threshold
// Result is face area information. It includes left, top, width, height, confidence
const res = await faceDetector.detect(
    imgEle,
    { shrink: 0.4, threshold: 0.6 }
);

Run Demo

1. Execute in the current directory

npm install
npm run dev

2. Visit http://0.0.0.0:8867

Performance

• multi small-sized face

• single big-sized face

Postprocess

This model has a better recognition effect for small-sized faces, and the image will be shrink before prediction, so it is necessary to transform the prediction output data.

The red line indicates the predicted output result, and the green line indicates the converted result. dx dy fw fh are known parameters.
