I am testing http://soft-matter.github.io/trackpy/stable/
You can access my image data here: http://goo.gl/fMv5oE
My code for tracking objects in subsequent video images is:
import matplotlib.pyplot as plt
plt.rcParams['image.cmap'] = 'gray' # Set grayscale images as default.
import trackpy as tp
v = pims.ImageSequence('F:/*.png')
f = tp.batch(v[:100],diameter=21,threshold=25)
t = tp.link_df(f, 5)
As a rule of thumb you can serialize objects using Pickle.
Also looking at the documentation o TrackPy you can find some ways to store data as a Panda matrix.
