3D Steganalysis Using Laplacian Smoothing at Various Levels

Abstract

3D objects are becoming ubiquitous while being used by many mobile and social network applications. Meanwhile, such objects are also becoming a channel being used for covert communication. Steganalysis aims to identify when information is transferred in such ways. This research study analyses the influence of the 3D object smoothing, which is an essential step before extracting the features used for 3D steganalysis. During the experimental results, the efficiency when employing various degrees of 3D smoothing, is assessed in the context of steganalysis.
