Efficient Depth Map Compression Exploiting Segmented Color Data
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.
