• SunPositionCalculator - Calculates the sun position given time of day and latitude.
• PolAngle_Model - Calculates the angle of polarisation for a zenith-centred hemisphere based on either the single or double-scattering sky polarisation model. Use in conjunction with SunPosCalculator to generate a model for a particular time and latitude.
• PolDegree - Calculates the polarisation degree for the sky hemisphere, given the solar azimuthal angle and elevation. Use in conjunction with SunPosCalculator to generate a model for a particular time and latitude. Uses only the single-scattering sky model.
• StokesReconstruction - Reconstructs the polarisation angle and degree based on four orthogonal images (can be colour or greyscale), using the Stokes equations.
• IntensityReconstruction - Reconstructs the polarisation angle and degree based on four not-necessarily orthogonal images (can be colour or greyscale). Requires knowledge of the angle offsets between images.
• AngleDegree_Image_Combo - Combines the polarisation angle and degree into a single image, where the colour scheme represents the angle and the brightness represents the degree. Use in conjunction with StokesReconstruction or ImageReconstruction to generate images straight from raw footage.

a GUI-based set of functions designed to track the location and axial angle of objects in cluttered environments. Can be used on manual or automatic settings.

Locust Wing-beat tracker - a GUI designed to track the position of a locust wing in a series of black-and-white video images, and read the wingbeat periodicity from a digital display. As it stands, probably too finely tuned and esoteric to be much use to anyone, but some of the functions may be usefully repurposed.
