1. [Chinese README](https://zhuanlan.zhihu.com/p/72617098) 2. [Chinese Source Code Analysis](https://zhuanlan.zhihu.com/p/74438078) ## Updated | Date | Update | | -- | -- | | 2022-07-23 | New: Use an Experimental Worker on iOS. Please see the "Image AR and 3D Mask". Fixed Issue: "Image AR" cannot run on iOS for a while. | | 2021-12-11 | New: Added a Image Tracker using OpenCV WebAssembly. Please see the "Image AR using OpenCV". | | 2021-09-07 | New: Added a Color Tracker mode. Please see the "Color AR". | | 2021-08-15 | New: Added a video mask mode for image AR. This is a CSS 3D transformation, which does not require three.js. Please see the "Image AR and Video Mask". Update: Replace the spirit geometry with a plane geometry. | | 2021-04-03 | Update: The "access a camera" mode of Image AR is recoverd. | | 2021-03-15 | New: The display of the AR mask is changed from 2D to 3D by three.js. Update: Because the "access a camera" mode is slow, it is removed. | | 2019-08-16 | Update: The project structure has been modified. The color tracker and object tracker are removed. Fix "access a camera" mode that does not work properly on Android. | | 2019-08-06 | Fix Issue: When function "wx.canvasToTempFilePath" is called frequently on Android Wechat, WeChat will be crashed. | | 2019-08-01 | Update: The perspective transform is achieved. | | 2019-07-15 | Update: The NFT(Natural Feature Tracking) is achieved. | | 2019-07-08 | New: The affine transform is achieved. | ## Introduction on WeChat Web AR This is a WeChat Web AR. On July 5, 2019, WeChat miniprogram supported AR. It was added a new API named "CameraFrameListener". [CameraFrameListener API](https://developers.weixin.qq.com/miniprogram/dev/api/media/camera/CameraContext.onCameraFrame.html) We can create AR effects with the new API. This demo demonstrates a AR tracker effect 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/) Index Page of the WeChat Mini-program   ## Image AR and 3D Mask iOS Wechat version number 8.0.24 or above：It will use an Experimental Worker. Android and other: It will not use an Experimental Worker. Use the demo to scan a pattern image below.  A cat beard is on the pattern image.  A effect of translating and scaling.  A effect of rotating.  ## Image AR using OpenCV This is the same as above. Supports image rotation. The image is rotated by 30 degrees.  The image is rotated by 90 degrees.  ## Image AR and Video Mask Use the demo to scan a rotating image below.  A video player is on and aligned with the image.  ## Color AR Use the demo to scan a yellow color. Expect a effect below.  A effect of hiddening.  Custom the color of the highlighted area.  ## Face AR Use the demo to scan a face. Expect a effect below.  A effect of translating and scaling.  Because the landmarks of the demo are simple and basic, only a effect of translating and scaling is on a rotating image.  ## How to replace the "cat beard" image You may replace the default url of a image for 2D mask. File: /package_image_tracker/pages/photo/photo.js and package_face_tracker/pages/photo/photo.js ```javascript // a url of sprite image const modelUrl = '../../utils/cat_beard.png'; ``` The width and h
