TitleLocal Background Sprite Generation
AbstractBackground modeling of video sequences can be used in
many different applications. For video object segmentation
it is often applied in a background subtraction method.
When conventional sprites like single or multiple sprites
are used a background sequence has to be reconstructed
from the model. The double mapping into the coordinate
system of the sprite and back can lead to severe distortion
of the background model and therefore to erroneous segmentation masks. We present a novel background modeling
approach that lessens distortion. These so-called local
background sprites are built for every reference frame independently and fit its original size. Experimental results show that this new approach clearly outperforms conventional background sprites in terms of PSNR.
