running ddm on a series of frames smaller than the full-frame has been called multi-ddm. this is analogous to changing the scattering volume in a light scattering experiment, but is readily carried out by selecting out of the full-frame movie. the coherence lengthscale of the dynamics can be picked up from a multi-ddm ...
