Abstract :
A robust blind watermarking algorithm of 3D models based on Octree partition is proposed: OTP-W. Primary Component Analysis and Octree partition are used on 3D meshes. A scrambled RGB image is embedded adaptively into the single child nodes at the bottom level of Octree structure. The watermark can be extracted without the original image and 3D model. This method has a high embedding capacity for arbitrary mesh and is robust against geometric transformation (like translation, rotation, uniform scaling) and vertex reordering attacks.
