AbstractPervasive multimedia devices require accurate video retargeting,
especially in connected consumer electronics platforms.
In this paper, we present a context assisted spatialtemporal
grid scheme for consumer video retargeting. First,
we parse consumer videos from low-level features to highlevel
visual concepts, combining visual attention into a more
accurate importance description. Then, a semantic importance
map is built up representing the spatial importance
and temporal continuity, which is incorporated with a 3D
rectilinear grid scaleplate to map frames to the target display,
thereby keeping the aspect ratio of semantically salient
objects as well as the perceptual coherency. Extensive evaluations
were done on two popular video genres, sports and
advertisements. The comparison with state-of-the-art approaches
on both images and videos have demonstrated the
advantages of the proposed approach.
