Implication

Perceptual evaluation study demonstrates superior visual quality assessment for textured 3D models using combined metrics, indicating improved alignment with human judgment.

Key Points

Investigate how humans perceive visual distortions on textured 3D meshes to develop objective quality assessment metrics that correlate strongly with human judgment.
Generated a database of 136 distorted models by applying both geometric and texture artifacts to 5 reference 3D meshes.
Conducted a subjective perceptual evaluation using a paired comparison protocol across two distinct rendering setups.
Engineered two objective quality metrics formulated as optimized linear combinations of individual geometry and texture measurements.
The proposed dual-attribute perceptual metrics outperformed existing quality models in correlation with subjective human ratings.
Distortions in both geometric surfaces and mapped texture images were shown to interactively dictate perceived visual quality.
Created an open-access benchmark repository containing 136 distorted textured meshes and their corresponding subjective quality scores.
