Notepad/enter/Step 2. Program for facial feature Comparison.md

If you already have the reference face (like the user profile picture), extract the descriptor of both the selfie and the reference image, and compare them.

async function compareFaces(image1, image2) {
    const detections1 = await detectFace(image1);
    const detections2 = await detectFace(image2);
    
    if (!detections1 || !detections2) {
        return false;  // No face detected
    }

    const distance = faceapi.euclideanDistance(
        detections1.descriptor, detections2.descriptor
    );

    const MATCH_THRESHOLD = 0.6;  // Set an appropriate threshold
    return distance < MATCH_THRESHOLD;  // If distance is below the threshold, the faces match
}
