A Multiscale Metric for 3D Mesh Visual Quality Assessment

Guillaume Lavoué
2011 Computer graphics forum (Print)  
In that context we introduce a full-reference 3D mesh quality metric; this metric can compare two meshes with arbitrary connectivity or sampling density and produces a score that predicts the distortion  ...  like the Hausdorff distance and the root mean square error, however these measures do not correlate with the human visual perception while the visual quality of the processed meshes is a crucial issue.  ...  In that context we propose a multiscale metric for objective quality assessment of 3D mesh.  ...
