YOLO video detection in the TouchDesigner

Description

This project demonstrate how to use custom ML model in the TouchDesigner. The solution consists from two components:

1. Script TOP in the TouchDesigner.
2. External process to process data.

sequenceDiagram
    participant T as TouchDesigner
    participant S as Shared memory
    participant P as Python external process
    T->>S: Send frame to shared memory
    S->>P: Read frame from shared memory
    P->>S: Process frame and write to shared memory
    S->>T: Read processed frame from shared memory

Loading

Requirements

1. Python 3.9 or higher. It is more preferable to have same version as in the TouchDesigner.

How to run

Install prebuild package from PyPi

From source

Install dependencies

For GPU:

pip install -r. /requirements.gpu.txt

For CPU:

pip install -r. /requirements.cpu.txt

For development:

pip install -r ./requirements.dev.txt

Compile Cython extension

You need C compiler to compile extension.

Develop mode

pip install -e .

Binary distribution

To compile binary distribution:

python -m cibuildwheel --platform <your_platform>

Install binary distribution:

pip install ./dist/*.whl

Usecases

Video detection

Run:

python ./main.py -c <checkpoint_path> -i <video_path> -o <video_path>

With TouchDesigner

Run server processing:

python ./processing.py -p <path_to_model>

Open touch_designer.py in the TouchDesigner as script TOP.
