|
## Quick Start
|
|
|
|
Simply load `Human` (*IIFE version*) directly from a cloud CDN in your HTML file:
|
|
(pick one: `jsdelirv`, `unpkg` or `cdnjs`)
|
|
|
|
```html
|
|
<script src="https://cdn.jsdelivr.net/npm/@vladmandic/human/dist/human.js"></script>
|
|
<script src="https://unpkg.dev/@vladmandic/human/dist/human.js"></script>
|
|
<script src="https://cdnjs.cloudflare.com/ajax/libs/human/2.1.4/human.js"></script>
|
|
```
|
|
|
|
For details, including how to use `Browser ESM` version or `NodeJS` version of `Human`, see [**Installation**](https://github.com/vladmandic/human/wiki/Install)
|
|
|
|
<br>
|
|
|
|
## 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 `<video>` tag that links to:
|
|
|
|
- WebCam on user's system
|
|
- Any supported video type
|
|
For example: `.mp4`, `.avi`, etc.
|
|
- Additional video types supported via *HTML5 Media Source Extensions*
|
|
Live streaming examples:
|
|
- **HLS** (*HTTP Live Streaming*) using `hls.js`
|
|
- **DASH** (Dynamic Adaptive Streaming over HTTP) using `dash.js`
|
|
- **WebRTC** media track using built-in support
|
|
|
|
<br>
|
|
|
|
## Example
|
|
|
|
Example 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(config);
|
|
|
|
function detectVideo() {
|
|
// select input HTMLVideoElement and output HTMLCanvasElement from page
|
|
const inputVideo = document.getElementById('video-id');
|
|
const outputCanvas = document.getElementById('canvas-id');
|
|
// 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);
|
|
});
|
|
}
|
|
|
|
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
|
|
|
|
async function detectVideo() {
|
|
const inputVideo = document.getElementById('video-id');
|
|
const outputCanvas = document.getElementById('canvas-id');
|
|
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 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); // calculate next interpolated frame
|
|
human.draw.all(outputCanvas, interpolated); // draw the frame
|
|
}
|
|
requestAnimationFrame(drawVideo); // run draw loop
|
|
}
|
|
|
|
detectVideo(); // start detection loop
|
|
drawVideo(); // start draw loop
|
|
```
|
|
|
|
And for even better results, you can run detection in a separate web worker thread

|
|
|
Default models in Human library are:
|
|
|
|
- **Face Detection**: MediaPipe BlazeFace - Back variation
|
|
- **Face Mesh**: MediaPipe FaceMesh
|
|
- **Face Iris Analysis**: MediaPipe Iris
|
|
