Abstract:In this paper, a new simple, adaptive, high-capacity steganographic algorithm for 3D models using contour theory in spatial domain is proposed. Every vertex of a 3D model can adaptively embed variable 3σ ( 1 σ ≥ ) bits using contour space subdivision and multi quantization index modulation (MQIM) with low distortion. We first use vertex weight estimation which is used to estimate the degree of smoothness or roughness properties of 3D model with respect to human visual system and adaptive embedding estimation t… Show more
