PyPTV

Python GUI for the OpenPTV library liboptv

PyPTV or otherwise called OpenPTV-Python is the Python GUI for OpenPTV. It is based on traits, traitsui, chaco, enable and pyface from Enthought Inc. and provides an UI interface the OpenPTV library that includes all the core algorithms (correspondence, tracking, calibration, etc.) written in ANSI C and has Python bindings using Cython.

Both PyPTV and the OpenPTV library are in the development phase and continuously refactored. Please follow the development on the community mailing list:

Working with plugins

Plugins is a system of extensions to PyPTV without the need to change the GUI

1. copy the sequence_plugins.txt and tracking_plugins.txt to the working folder
2. copy the plugins/ directory to the working folder
3. modify the code so it performs instead of the default sequence or default tracker
4. Open the GUI and Plugins -> Choose , then run the rest: Init -> Sequence

Note, the specific branch plugin_remback requires installation of the pip install rembg[cpu] or pip install rembg[gpu]
