WebJun 21, 2012 · We compare two recent approaches to estimate the diffusion coefficient from a single-particle trajectory in the presence of localization error and motion blur for the case of isotropic Brownian diffusion. We show that both methods approach the theoretical limit on diffusion coefficient uncertainty given by the Cramér-Rao lower bound. WebOptimal tracking of a Brownian particle Alexander P.
