This repository is a system adaptation of Talking Head Anime 3 Demo for AITuber. It possesses the following features:

• Generates random Live 2D-like motion actions from a single static image.
• Lip-syncs to the sound output from the PC (mouth movement).

The audio device at index 0 is selected by default. Please align this with the audio device that outputs the AITuber's voice.

We recommend using a virtual audio device such as VB-CABLE to output the AITuber's voice.

Firstly, please set up original talking head anime3 demo and install the following packages additionally.

pip install sounddevice

And then, please run the following command instead of ifacialmocap_puppeteer.py .

python tha3/app/random_puppet.py

The original window will appear. Please set the image of the character you want to animate.

If you use Mac, replace conda environment creation command with the following command and use pythonw command alternatively.

-) conda create -n talking-head-anime-3-demo python=3.8
+) conda create -n talking-head-anime-3-demo python.app python=3.8

And then, it is needed to change tha3/app/random_puppet.py as follows.

-) device = torch.device('cuda')
+) device = torch.device('cpu')

Following is the original README.md.

This repository contains demo programs for the Talking Head(?) Anime from a Single Image 3: Now the Body Too project. As the name implies, the project allows you to animate anime characters, and you only need a single image of that character to do so. There are two demo programs:

• The manual_poser lets you manipulate a character's facial expression, head rotation, body rotation, and chest expansion due to breathing through a graphical user interface.
• ifacialmocap_puppeteer lets you transfer your facial motion to an anime character.

If you do not have the required hardware (discussed below) or do not want to download the code and set up an environment to run it, click to try running the manual poser on Google Colab.

Both programs require a recent and powerful Nvidia GPU to run. I could personally ran them at good speed with the Nvidia Titan RTX. However, I think recent high-end gaming GPUs such as the RTX 2080, the RTX 3080, or better would do just as well.

The ifacialmocap_puppeteer requires an iOS device that is capable of computing blend shape parameters from a video feed. This means that the device must be able to run iOS 11.0 or higher and must have a TrueDepth front-facing camera. (See this page for more info.) In other words, if you have the iPhone X or something better, you should be all set. Personally, I have used an iPhone 12 mini.

Please update your GPU's device driver and install the CUDA Toolkit that is compatible with your GPU and is newer than the version you will be installing in the next subsection.

Both manual_poser and ifacialmocap_puppeteer are available as desktop applications. To run them, you need to set up an environment for running programs written in the Python language. The environment needs to have the following software packages:

• Python >= 3.8
• PyTorch >= 1.11.0 with CUDA support
• SciPY >= 1.7.3
• wxPython >= 4.1.1
• Matplotlib >= 3.5.1

One way to do so is to install Anaconda and run the following commands in your shell:

> conda create -n talking-head-anime-3-demo python=3.8
> conda activate talking-head-anime-3-demo
> conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
> conda install scipy
> pip install wxpython
> conda install matplotlib

As of June 2006, you cannot use wxPython with Python 3.10 on Windows. As a result, do not use Python 3.10 until this bug is fixed. This means you should not set python=3.10 in the first conda command in the listing above.

The environment created by the commands above gives you Python version 3.8 and an installation of PyTorch that was compiled with CUDA Toolkit version 11.3. This particular setup might not work in the future because you may find that this particular PyTorch package does not work with your new computer. The solution is to:

1. Change the Python version in the first command to a recent one that works for your OS. (That is, do not use 3.10 if you are using Windows.)
2. Change the version of CUDA toolkit in the third command to one that the PyTorch's website says is available. In particular, scroll to the "Install PyTorch" section and use the chooser there to pick the right command for your computer. Use that command to install PyTorch instead of the third command above.

The manual_poser is also available as a Jupyter Nootbook. To run it on your local machines, you also need to install:

• Jupyter Notebook >= 7.3.4
• IPywidgets >= 7.7.0

In some case, you will also need to enable the widgetsnbextension as well. So, run

> jupyter nbextension enable --py widgetsnbextension

After installing the above two packages. Using Anaconda, I managed to do the above with the following commands:

> conda install -c conda-forge notebook
> conda install -c conda-forge ipywidgets
> jupyter nbextension enable --py widgetsnbextension

You can also use Anaconda to download and install all Python packages in one command. Open your shell, change the directory to where you clone the repository, and run:

> conda env create -f environment.yml

This will create an environment called talking-head-anime-3-demo containing all the required Python packages.

If you want to use ifacialmocap_puppeteer, you will also need to an iOS software called iFacialMocap (a 980 yen purchase in the App Store). You do not need to download the paired application this time. Your iOS and your computer must use the same network. For example, you may connect them to the same wireless router.

Before running the programs, you need to download the model files from this Dropbox link and unzip it to the data/models folder under the repository's root directory. In the end, the data folder should look like:

      - two_algo_face_body_rotator.pt
    + standard_half
      - editor.pt
          :
      - two_algo_face_body_rotator.pt

Open a shell. Change your working directory to the repository's root directory. Then, run:

> python tha3/app/manual_poser.py

Note that before running the command above, you might have to activate the Python environment that contains the required packages. If you created an environment using Anaconda as was discussed above, you need to run

> conda activate talking-head-anime-3-demo

if you have not already activated the environment.

As noted in the project's write-up, I created 4 variants of the neural network system. They are called standard_float, separable_float, standard_half, and separable_half. All of them have the same functionalities, but they differ in their sizes, RAM usage, speed, and accuracy. You can specify which variant that the manual_poser program uses through the --model command line option.

> python tha3/app/manual_poser --model <variant_name>

where <variant_name> must be one of the 4 names above. If no variant is specified, the standard_float variant (which is the largest, slowest, and most accurate) will be used.

Open a shell. Activate the environment. Change your working directory to the repository's root directory. Then, run:

> jupyter notebook

A browser window should open. In it, open manual_poser.ipynb. Once you have done so, you should see that it has two cells. Run the two cells in order. Then, scroll down to the end of the document, and you'll see the GUI there.

You can choose the system variant to use by changing the MODEL_NAME variable in the first cell. If you do, you will need to rerun both cells in order for the variant to be loaded and the GUI to be properly updated to use it.

First, run iFacialMocap on your iOS device. It should show you the device's IP address. Jot it down. Keep the app open.

Open a shell. Activate the Python environment. Change your working directory to the repository's root directory. Then, run:

> python tha3/app/ifacialmocap_puppeteer.py

You will see a text box with label "Capture Device IP." Write the iOS device's IP address that you jotted down there.

Click the "START CAPTURE!" button to the right.

If the programs are connected properly, you should see the numbers in the bottom part of the window change when you move your head.

Now, you can load an image of a character, and it should follow your facial movement.

In order for the system to work well, the input image must obey the following constraints:

• It should be of resolution 512 x 512. (If the demo programs receives an input image of any other size, they will resize the image to this resolution and also output at this resolution.)
• It must have an alpha channel.
• It must contain only one humanoid character.
• The character should be standing upright and facing forward.
• The character's hands should be below and far from the head.
• The head of the character should roughly be contained in the 128 x 128 box in the middle of the top half of the image.
• The alpha channels of all pixels that do not belong to the character (i.e., background pixels) must be 0.

See the project's write-up for more details on the input image.
