Pyimof (for Python image optical flow) is a pure python package for dense optical flow estimation. A good introduction to optical flow techniques can be found here.

Quick Example

Using Pyimov is as easy as

>>> from matplotlib import pyplot as plt
>>> import pyimof
>>> I0, I1 =
>>> u, v = pyimof.solvers.tvl1(I0, I1)
>>> pyimof.display.plot(u, v)
