On a spatial-temporal decomposition of the optical flow
In this paper we present a decomposition algorithm for computation of the
spatial-temporal optical flow of a dynamic image sequence. We consider several
applications, such as the extraction of temporal motion features and motion
detection in dynamic sequences under varying illumination conditions, such as
they appear for instance in psychological flickering experiments. For the
numerical implementation we are solving an integro-differential equation by a
fixed point iteration. For comparison purposes we use a standard time dependent
optical flow algorithm, which in contrast to our method, constitutes in solving
a spatial-temporal differential equation
