hand and cell phone

[rickmaz]

I am using web version code here is is below. i am trying to get the right config and can not tell from the docs if it is even possible (not using node.js or backend) i would like to be able to detect if hands or fingers are in the webcam input and mobile phone if someone holding up image of a face on a phone for example: <script type="module">
import Human from 'https://cdn.jsdelivr.net/npm/@vladmandic/[email protected]/dist/human.esm.js';

    document.addEventListener('DOMContentLoaded', async () => {
		
        const video = document.getElementById('video');
        const canvas = document.getElementById('canvas');
        const photo = document.getElementById('photo');
        const snap = document.getElementById('snap');
        const uploadForm = document.getElementById('uploadForm');
        const uploadButton = uploadForm.querySelector('button');
        const imageDataInput = document.getElementById('imageData');
        const instructions = document.getElementById('instructions');
		const ageStats = document.getElementById('ageStats');
        const progressBar = document.getElementById('progressBar');
        const progressCount = document.getElementById('progressCount');
		
		const DEBUG_MODE = false;
		toggleDebugInfo();
		
		const ANGLE_THRESHOLD_LOW = -0.25;
		const ANGLE_THRESHOLD_HIGH = 0.25;
		const GAZE_STRENGTH_THRESHOLD = 0.2;
		const MIN_ACCEPTABLE_DISTANCE = 0.65; // Adjust this value as needed
		const MAX_ACCEPTABLE_DISTANCE = 1.30; // Adjust this value as needed
		const MAX_DISTANCE_FOR_GOOD_PHOTO = 1.25;
					
		// Initialize session variables in JavaScript
        let ageLogs = [];
        let isSnapped = false;
        let step1_ageCount = 0;
        let step1_avgAge = 0;
        let step1_minAge = 999;
        let step1_maxAge = 0;
		
		let intervalId = null;
		let isPhotoTaken = false;
		
        const humanConfig = {
            modelBasePath: 'https://cdn.jsdelivr.net/npm/@vladmandic/[email protected]/models',
            async: true,
             face: { 
			enabled: true,
			detector: { rotation: true },
			mesh: { enabled: true },
			iris: { enabled: true },
			description: { enabled: true },
			liveness: { enabled: true },
			antispoof: { enabled: true, threshold: 0.5 } },
            age: { enabled: true },
            filter: { enabled: true, flip: true }
        };
        
        const human = new Human(humanConfig);

if i understood correctly, then only partial fingers would be visible while holding the phone and palm of the hand would be obstructed by the phone - none of the hand detection models would detect hand with any kind of confidence in that case.
