## Introduction of Web AR

This is a Web AR Demo.

We can create AR effects by using "tracking.js" and "jsfeat" library.

The "tracking.js" brings computer vision algorithms and techniques into browser environment. The "jsfeat" is also a JavaScript computer vision library. We can do real-time image and face detection.

[tracking.js](https://trackingjs.com/) and [JSFeat](https://inspirit.github.io/jsfeat/)

## Image AR using OpenCV

This is the same as above. Supports image rotation.

The image is rotated by 30 degrees.

![avatar](https://raw.githubusercontent.com/sanyuered/WebAR/main/screenshot/5-1.jpg)

The image is rotated by 90 degrees.

## How to replace the 2D mask "cat beard"

You may replace the default url of a image for 2D mask.

File: /package_image_tracker/photo/photo.js and
/package_image_tracker/camera/camera.js

```javascript
const modelUrl = '../../assets/cat_beard.png';
```

## How to replace the pattern image

File: /package_face_tracker/utils/imageBusiness.js

```javascript
const patternImageUrl = '../../assets/face_pattern.jpg';
```

A pattern image is below.

## How to put a image on an other position

Select a track point on a pattern image, the point is used to set the "cat beard" image.

File: /package_image_tracker/utils/modelBusiness.js

```javascript
// a index of a track point on a pattern image
const trackPoint = { 
    x: 186, // the width of the pattern image is 375
    y: 140, // the height of the pattern image is 375
};
```
