## Quick Start
Simply load `Human` (*IIFE version*) directly from a cloud CDN in your HTML file:
(pick one: `jsdelirv`, `unpkg` or `cdnjs`)```html
```
For details, including how to use `Browser ESM` version or `NodeJS` version of `Human`, see [**Installation**](https://github.com/vladmandic/human/wiki/Install)
## Code Examples
Simple app that uses Human to process video input and
draw output on screen using internal draw helper functions```js
// create instance of human with simple configuration using default values
const config = { backend: 'webgl' };
const human = new Human.Human(config);
// select input HTMLVideoElement and output HTMLCanvasElement from page
const inputVideo = document.getElementById('video-id');
const outputCanvas = document.getElementById('canvas-id');function detectVideo() {
// perform processing using default configuration
human.detect(inputVideo).then((result) => {
// result object will contain detected details
// as well as the processed canvas itself
// so lets first draw processed frame on canvas
human.draw.canvas(result.canvas, outputCanvas);
// then draw results on the same canvas
human.draw.face(outputCanvas, result.face);
human.draw.body(outputCanvas, result.body);
human.draw.hand(outputCanvas, result.hand);
human.draw.gesture(outputCanvas, result.gesture);
// and loop immediate to the next frame
requestAnimationFrame(detectVideo);
return result;
});
}detectVideo();
```or using `async/await`:
```js
// create instance of human with simple configuration using default values
const config = { backend: 'webgl' };
const human = new Human(config); // create instance of Human
const inputVideo = document.getElementById('video-id');
const outputCanvas = document.getElementById('canvas-id');async function detectVideo() {
const result = await human.detect(inputVideo); // run detection
human.draw.all(outputCanvas, result); // draw all results
requestAnimationFrame(detectVideo); // run loop
}detectVideo(); // start loop
```or using `Events`:
```js
// create instance of human with simple configuration using default values
const config = { backend: 'webgl' };
const human = new Human(config); // create instance of Human
const inputVideo = document.getElementById('video-id');
const outputCanvas = document.getElementById('canvas-id');human.events.addEventListener('detect', () => { // event gets triggered when detect is complete
human.draw.all(outputCanvas, human.result); // draw all results
});function detectVideo() {
human.detect(inputVideo) // run detection
.then(() => requestAnimationFrame(detectVideo)); // upon detect complete start processing of the next frame
}detectVideo(); // start loop
```or using interpolated results for smooth video processing by separating detection and drawing loops:
```js
const human = new Human(); // create instance of Human
const inputVideo = document.getElementById('video-id');
const outputCanvas = document.getElementById('canvas-id');
let result;async function detectVideo() {
result = await human.detect(inputVideo); // run detection
requestAnimationFrame(detectVideo); // run detect loop
}async function drawVideo() {
if (result) { // check if result is available
const interpolated = human.next(result); // get smoothened result using last-known results
human.draw.all(outputCanvas, interpolated); // draw the frame
}
requestAnimationFrame(drawVideo); // run draw loop
}detectVideo(); // start detection loop
drawVideo(); // start draw loop
```or same, but using built-in full video processing instead of running manual frame-by-frame loop:
```js
const human = new Human(); // create instance of Human
const inputVideo = document.getElementById('video-id');
const outputCanvas = document.getElementById('canvas-id');async function drawResults() {
const interpolated = human.next(); // get smoothened result using last-known results
human.draw.all(outputCanvas, interpolated); // draw the frame
requestAnimationFrame(drawResults); // run draw loop
}human.video(inputVideo); // start detection loop which continously updates results
drawResults(); // start draw loop
```or using built-in webcam helper methods that take care of video handling completely:
```js
const human = new Human(); // create instance of Human
const outputCanvas = document.getElementById('canvas-id');async function drawResults() {
const interpolated = human.next(); // get smoothened result using last-known results
human.draw.canvas(outputCanvas, human.webcam.element); // draw current webcam frame
human.draw.all(outputCanvas, interpolated); // draw the frame detectgion results
requestAnimationFrame(drawResults); // run draw loop
}await human.webcam.start({ crop: true });
human.video(human.webcam.element); // start detection loop which continously updates results
drawResults(); // start draw loop
```And for even better results, you can run detection in a separate web worker thread
## Inputs
`Human` library can process all known input types:
- `Image`, `ImageData`, `ImageBitmap`, `Canvas`, `OffscreenCanvas`, `Tensor`,
- `HTMLImageElement`, `HTMLCanvasElement`, `HTMLVideoElement`, `HTMLMediaElement`Additionally, `HTMLVideoElement`, `HTMLMediaElement` can be a standard `` tag that links to:
- WebCam on user's system
- Any supported video type
e.g. `.mp4`, `.avi`, etc.
- Additional video types supported via *HTML5 Media Source Extensions*
e.g.: **HLS** (*HTTP Live Streaming*) using `hls.js` or **DASH** (*Dynamic Adaptive Streaming over HTTP*) using `dash.js`
- **WebRTC** media track using built-in support
## Detailed Usage
- [**Wiki Home**](https://github.com/vladmandic/human/wiki)
- [**List of all available methods, properies and namespaces**](https://github.com/vladmandic/human/wiki/Usage)
- [**TypeDoc API Specification - Main class**](https://vladmandic.github.io/human/typedoc/classes/Human.html)
- [**TypeDoc API Specification - Full**](https://vladmandic.github.io/human/typedoc/)
## TypeDefs
`Human` is written using TypeScript strong typing and ships with full **TypeDefs** for all classes defined by the library bundled in `types/human.d.ts` and enabled by default
*Note*: This does not include embedded `tfjs`
If you want to use embedded `tfjs` inside `Human` (`human.tf` namespace) and still full **typedefs**, add this code:> import type * as tfjs from '@vladmandic/human/dist/tfjs.esm';
> const tf = human.tf as typeof tfjs;This is not enabled by default as `Human` does not ship with full **TFJS TypeDefs** due to size considerations
Enabling `tfjs` TypeDefs as above creates additional project (dev-only as only types are required) dependencies as defined in `@vladmandic/human/dist/tfjs.esm.d.ts`:> @tensorflow/tfjs-core, @tensorflow/tfjs-converter, @tensorflow/tfjs-backend-wasm, @tensorflow/tfjs-backend-webgl
## Default models
Default models in Human library are:
- **Face Detection**: *MediaPipe BlazeFace Back variation*
- **Face Mesh**: *MediaPipe FaceMesh*
- **Face Iris Analysis**: *MediaPipe Iris*
- **Face Description**: *HSE FaceRes*
- **Emotion Detection**: *Oarriaga Emotion*
- **Body Analysis**: *MoveNet Lightning variation*
- **Hand Analysis**: *HandTrack & MediaPipe HandLandmarks*
- **Body Segmentation**: *Google Selfie*
- **Object Detection**: *CenterNet with MobileNet v3*Note that alternative models are provided and can be enabled via configuration
For example, body pose detection by default uses *MoveNet Lightning*, but can be switched to *MultiNet Thunder* for higher precision or *Multinet MultiPose* for multi-person detection or even *PoseNet*, *BlazePose* or *EfficientPose* depending on the use caseFor more info, see [**Configuration Details**](https://github.com/vladmandic/human/wiki/Configuration) and [**List of Models**](https://github.com/vladmandic/human/wiki/Models)
## Diagnostics
