Corsini M., Drelie Gelasca E., Ebrahimi T., Barni M. Watermarked 3-D Mesh Quality Assessment. In: Ieee Transactions on Multimedia, vol. 9 (2) pp. 247 - 256. IEEE Signal Processing Society, 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-D watermarking is assessed and compared with the state of the art. Results obtained showgood correlations between the proposed objective metrics and subjective assessments by human observers.
