We present a coding and quality evaluation method for Six Degrees of Freedom (6DoF) video content. Firstly, the 6DoF video content is generated using an affordable capturing setup, and represented as the commonly used 6DoF format 3-D mesh. To overcome the difficulty in exploiting the temporal redundancy in mesh with different connectivity at every frame, we transform the mesh sequence into colored point clouds for compression, which saves the bit budget for connectivity while keeping the photo-realistic characteristics of the 3-D object. We compress the point cloud sequence using MPEG video-based point cloud compression structure, which can achieve the bit rate close to common media format. We also conduct projection-based and point-based quality evaluation to examine the compression distortion effect. Particularly, we employ PCA to find the representative viewing perspective for projection. We will release some data set and source codes to foster further research in this area.
