Tracking a single frame (image)

[luispuig]

Hello,

We are using this solution for webcam video tracking. Currently, we have an extra need, processing an image using BRFv5 to get the 68 points. First, we transform the image to 640x480 pixels and we make sure that the face is centred and with good size. But:

• The face is not detected many times
• When the face is detected, we process the image BRFManager.update() 10 times with different 68 points coordinates values.

Which configuration should we use?

I share an image as an example of face not detected.

// 640 x 480 
const BRF = await BRFv5.createInstance({ width, height, uniqueFrame: true });
const canvas = document.createElement('canvas');
canvas.width = width;
canvas.height = height;
context.drawImage(imageElement, 0, 0, width, height);
const imageData = context.getImageData(0, 0, width, height);

for (let index = 0; index < 10; index += 1) {
        BRF.Manager.update(imageData);
}

const faces = BRF.Manager.getFaces();

const isFaceDetected =
        faces.length > 0 &&
        (faces[0].state === BRF.Instance.BRFv5State.FACE_TRACKING_START ||
          faces[0].state === BRF.Instance.BRFv5State.FACE_TRACKING);

if (isFaceDetected) {
     return resolve(faces[0].vertices);
}
const error = new Error('No face detected');
error.code = 999;
return reject(error);
