Abstract
Gradient methods are widely used in the com-
putation of optical ow. We discuss extensions
of these methods which compute probability dis-
tributions of optical ow. The use of distribu-
tions allows representation of the uncertainties
inherent in the optical ow computation, facil-
itating the combination with information from
other sources. We compute distributed optical
ow for a synthetic image sequence and demon-
strate that the probabilistic model accounts for
the errors in the ow estimates. We also compute
distributed optical ow for a real image sequence.
