A free, multiplatform SDK for real-time facial motion capture using blendshapes, and rigid head pose in 3D space from any RGB camera, photo, or video.

Last update: Dec 27, 2022

Overview

mocap4face by Facemoji

mocap4face by Facemoji is a free, multiplatform SDK for real-time facial motion capture based on Facial Action Coding System or (FACS). It provides real-time FACS-derived blendshape coefficients, and rigid head pose in 3D space from any mobile camera, webcam, photo, or video enabling live animation of 3D avatars, digital characters, and more.

After fetching the input from one of the mentioned sources, mocap4face SDK produces data in ARKit-compatible blendshapes, i.e., morph targets weight values as a per-frame expression shown in the video below. Useful for, e.g., animating a 2D or 3D avatar in a way that mimics the user's facial expressions in real-time à la Apple Memoji but without the need of a hardware-based TrueDepth Camera.

With mocap4face, you can drive live avatars, build Snapchat-like lenses, AR experiences, face filters that trigger actions, VTubing apps, and more with as little energy impact and CPU/GPU use as possible. As an example, check out how the popular avatar live-streaming app REALITY is using our SDK.

Mainactivity re-opened cannot be traced
Only the first open MainActivity can be tracked. when back to SplashActivity and reopen Mainactivity the track result is null.

The test code is as follows（modify SplashAtivity）：

override fun onResume() { super.onResume() Timer("Splash", false).schedule(5000) { startMainActivity() } }

can not find any documents about how to build a app using facemoji SDK

i want to build a app like the offical facemoji app, but the demo code is so simple, the SDK even has no document.

can anyone tell me how to use the SDK to build a facemoji app ?

Fix "artifact not found for target 'mocap4face'" error
Issue

I got "artifact not found for target 'mocap4face'" error when I tried to load mocap4face Swift Package by Xcode 13.3

The target name should be exactly the same as the framework name (case sensitive)

Changes

Change the target name from mocap4face to Mocap4Face to match the framework name

Any plans for Windows & MacOS Support?

I'm guessing if this is already cross-platform on Android, Web, and iOS that this an upcoming features. Just curious since we'd love to use this everywhere if possible

[Question]: Is this Lib compatible with react-native?

It would be incredibly awesome to include this library in my React-Native start-up App but I wonder whether there's React-Native compatible SDK?

Thanks!!!

Stop face tracking

Hello. Thanks for the great face tracking library!

How can I stop tracking? Something like a dispose/destroy function?

I am using this library in web (js)

Status of macOS build?

Has any new work been done to bring this to the Mac via catalyst?

We primarily just want to be able to use the full camera width when running under M1 catalyst. We don't need the full feature-set, but macOS forces "non-mac" frameworks to use a cropped iPhone-like camera view even on the Mac which has a much wider view.
