In this paper an objective metric to measure the perceptual quality of watermarked 3D meshes is presented. The metric, which is based on a black-box approach, relies on the measurement of the roughness of 3D meshes before and after the insertion of the watermark. To calibrate the metric and to validate it, a set of psychovisual experiments has been carried out. Due to the lack of prior work in this field, a new methodology for the subjective evaluation of the quality of watermarked 3D objectsdoi:10.1109/icip.2005.1529732 dblp:conf/icip/GelascaECB05 fatcat:5dt4mf67dnhaxckgyuvql6lrnq
