Energy-Adaptive Bitstream-Layer Model for Perceptual Quality Assessment of V-PCC Encoded 3D Point Clouds.

The scope of point cloud (PC) applications is expanding. We propose a no-reference bitstream-layer quality assessment model that eliminates the need for full decoding of the PC, providing quality evaluation scores during the V-PCC decoding process. Specifically, we illustrate the relationship between content diversity (CD) and perceptual coding distortion in lossless geometric coding.
