This paper addresses the problem of assessing distortions produced by watermarking 3-D meshes. In particular, a new methodology for subjective evaluation of the quality of 3-D objects is proposed and implemented. Two objective metrics derived from measures of surface roughness are then proposed and their efficiency to predict the perceptual impact of 3-D watermarking is assessed and compared with the state of the art. Results obtained show good correlations between the proposed objective metrics and subjective assessments by human observers.

Abstract
This paper addresses the problem of assessing distortions produced by watermarking 3-D meshes. In particular, a new methodology for subjective evaluation of the quality of 3-D objects is proposed and implemented. Two objective metrics derived from measures of surface roughness are then proposed and their efficiency to predict the perceptual impact of 3-D watermarking is assessed and compared with the state of the art. Results obtained show good correlations between the proposed objective metrics and subjective assessments by human observers.Pubblicazioni consigliate
