BACKGROUND RECOVERY FROM VIDEO SEQUENCES USING MOTION PARAMETERS

This paper presents a novel scheme for extracting a still

background occluded by a number of foreground objects,

moving in different directions and velocities in a video

sequence, such that every background pixel is exposed in at

least one of the frames. Each identified foreground object is

decomposed into blocks. The proposed scheme is able to

efficiently estimate, for each foreground block, a source

frame from which the occluded background pixels can be

extracted. The pixels of the identified source frames are

used to populate the co-located occluded pixels in the initial

frame. The efficacy and the simplicity of the algorithm lie in

its capacity to recover the background directly from the

estimated source frames instead of performing a foregroundbackground

classification for every frame. The proposed

algorithm is robust to variations in lighting and is effective

in removing both rigid and deformable foreground objects.

Simulation results are presented to illustrate the

performance of the proposed scheme.
