  Video representation is an important and challenging task in the computer
vision community. In this paper, we assume that image frames of a moving scene
can be modeled as a Linear Dynamical System. We propose a sparse coding
framework, named adaptive video dictionary learning (AVDL), to model a video
adaptively. The developed framework is able to capture the dynamics of a moving
scene by exploring both sparse properties and the temporal correlations of
consecutive video frames. The proposed method is compared with state of the art
video processing methods on several benchmark data sequences, which exhibit
appearance changes and heavy occlusions.
