Pyctools

A picture processing algorithm development kit.

Pyctools is a collection of picture processing primitive components that you can easily interconnect to make complex algorithm simulations. It works with stills or video, and utilises popular libraries such as Python Imaging Library, NumPy and OpenCV.

Example projects using pyctools include pyctools-pal (a simulation of the Transform PAL decoder) and pyctools-demo (demonstrations of some simple processing).

Documentation

The core Pyctools library and components are documented on Read The Docs. If you install additional components you should build a local copy of the documentation to include the extra components.

Requirements

Essential

  • Python version 3.x. Much of Pyctools will work with Python 2.7 but I no longer worry about compatibility when adding new features.
  • NumPy for its powerful multi-dimensional array object.
  • Python Imaging Library for image file reading and writing. (The pillow fork of PIL is recommended.)
  • Cython to build fast extensions for Python.
  • python-exiv2 to handle metadata.

Optional

  • OpenCV python bindings for advanced image processing.
  • FFmpeg to read and write video files.
  • rawkit and/or rawpy to read raw image files.
  • PyQt5 and PyOpenGL graphic toolkit used by the Pyctools visual editor and the Qt display components.
  • Sphinx and mock to build local documentation.

Installation

Please see the documentation for full details of how to install Pyctools and its requirements.
