Subjective evaluation and objective measures for point clouds — State of the art

This paper presents a state of the art on subjective evaluation and existing objective quality measures for point cloud representations. A brief review on subjective evaluation protocols for 2D and 3D video quality assessment will be given, and its adaptation for point cloud evaluation described together with a description of existing point cloud objective quality measures. Afterwards, specific problems with subjective experiments and objective measures for point clouds will be discussed. Challenges and future research directions regarding point clouds quality assessment will be discussed.
