Point Cloud Quality Assessment Using the Perceptual Clustering Weighted Graph (PCW-Graph) and Attention Fusion Network

This addresses quality assessment for 3D point clouds in real-world applications where reference models are unavailable, but it appears incremental as it builds on existing NR-PCQA methods.

The paper tackles the problem of No-Reference Point Cloud Quality Assessment (NR-PCQA) for evaluating 3D content without reference models, but the abstract does not provide specific results or numbers.
