Watermarked 3-D Mesh Quality Assessment [PDF]

open access: yesIEEE Transactions on Multimedia, 2007
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-
