Abstract
3D video representations usually associate to each view a
depth map with the corresponding geometric information.
Many compression schemes have been proposed for multiview
video and for depth data, but the exploitation of the correlation
between the two representations to enhance compression
performances is still an open research issue. This paper
presents a novel compression scheme that exploits a segmentation
of the color data to predict the shape of the different
surfaces in the depth map. Then each segment is approximated
with a parameterized plane. In case the approximation
is sufficiently accurate for the target bit rate, the surface
coefficients are compressed and transmitted. Otherwise, the
region is coded using a standard H.264/AVC Intra coder. Experimental
results show that the proposed scheme permits to
outperformthe standardH.264/AVC Intra codec on depth data
and can be effectively included into multi-view plus depth
compression schemes.
