credits: Sham Tlili for the strain-rate measure.

The associated Mathematica functions for strain-rate measure are translations of her Matlab code

J.M (Stack Exchange) for the getEigenSystem implementation

Please note that you can also use the built-in EigenSystem function.

The script pyramidal-KLT.m is based on a pyramidal implementaion of Lucas Kanade motion tracking algorithm. It can be used to obtain flow-field at a given instance using consecutive images. The features to be tracked in the flow are taken as points inside a masked region.

VectorFieldOperations.m contains functions for computing velocity gradients and strain-rate from velocity-fields

pyramidal-KLT-allmethods.m is a merger of the two script files
