A Robust 3D-Based Color Correction Approach for Texture Mapping Applications
Sensors, 2022 Texture mapping of 3D models using multiple images often results in textured meshes with unappealing visual artifacts known as texture seams. These artifacts can be more or less visible, depending on the color similarity between the used images. The main

Perceptual Quality Metrics for 3D Meshes: Towards an Optimal Multi-attribute Computational Model [PDF]
2013 IEEE International Conference on Systems, Man, and Cybernetics, 2013 3D graphical data, commonly represented using triangular meshes, are deployed in a wide range of application processes including compression, filtering, watermarking, and simplification. These processes often introduce geometric distortions which affect the visual quality of the ultimate data visualization.

A Multiscale Metric for 3D Mesh Visual Quality Assessment [PDF]
Computer Graphics Forum, 2011 AbstractMany processing operations are nowadays applied on 3D meshes like compression, watermarking, remeshing and so forth; these processes are mostly driven and/or evaluated using simple distortion measures like the Hausdorff distance and the root mean square error, however these measures do not correlate with the human visual perception while the ...

A new mesh visual quality metric using saliency weighting-based pooling strategy [PDF]
Graphical Models, 2018 Abstract Several metrics have been proposed to assess the visual quality of 3D triangular meshes during the last decade. In this paper, we propose a mesh visual quality metric by integrating mesh saliency into mesh visual quality assessment. We use the Tensor-based Perceptual Distance Measure metric to estimate the local distortions for the mesh, and
