Abstract
Given the video of a still background occluded by a fluid
dynamic texture (FDT), this paper addresses the problem of
separating the video sequence into its two constituent lay-
ers. One layer corresponds to the video of the unoccluded
background, and the other to that of the dynamic texture,
as it would appear if viewed against a black background.
The model of the dynamic texture is unknown except that it
represents fluid flow. We present an approach that uses the
image motion information to simultaneously obtain a model
of the dynamic texture and separate it from the background
which is required to be still. Previous methods have consid-
ered occluding layers whose dynamics follows simple mo-
