Picture processing algorithm development kit

Project description

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.


  • Python version 2.7 or 3.x.
  • Guild for communicating components.
  • 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.
  • gexiv2 to handle metadata.
  • OpenCV python bindings (optional) for advanced image processing.
  • FFmpeg (optional) to read and write video files.


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