We study the coding efficiency of view synthesis prediction (VSP) in 3D video coding. Our spectral domain analysis relates the power spectral density (PSD) of the VSP prediction error to the probability density function (pdf) of the warping error. Our analysis takes into account the warping error induced by (i) depth coding and (ii) rounding error at integer-pel, half-pel and quarter-pel warping accuracy...
We study the efficiency of view synthesis prediction (VSP). The proposed spectral domain analysis relates the power spectral density of the VSP error to the probability density function of the warping error. The analysis takes into account the warping error induced by (i) depth coding and (ii) disparity rounding at integer-pel, half-pel and quarter-pel warping accuracy. The interaction between VSP...
In this paper, a novel spatial prediction method is proposed to improve prediction accuracy and capture the dynamics of different video contents. The method adaptively generates optimized spatial prediction modes according to the local feature of coded image. The optimization is conducted by analytical calculations to minimize the energy of prediction residue. Experimental results show that the method...
Land use change is the most significant aspect in the research field of globe changing. Affected by both of natural and artificial factors, the land use and land resources quality varied continually. Dongguan City where the zone has a typical feature of land use change and significant ecological effects is selected as a case. This paper analyzed the spatial conversion of arable land in Dongguan city...
