Abstract:As the main scheme of 3D scene representation, multiview video plus depth attracts more and more attention. Depth video reflects the geometric information of the scene. It is important to design fast depth video encoding algorithm. A fast depth video coding algorithm based on region division was proposed. Firstly, the depth video was divided into four regions according to the features of edge and motion. Then, macroblock distribution proportion and multi-reference frame selection feature of different regions were analyzed. Consequently, different macroblock mode decision and reference frame selection methods were utilized to speedup depth video encoding. Finally, some experiments were conducted to estimate the proposed algorithm in terms of encoding time, bit rate and virtual view quality. Experimental results show that the proposed algorithm saves encoding time ranging from 85.73% to 91.06% while it maintains virtual view quality and bit rate.
