摘要
A novel method for the watermarking of 3D models is proposed. which is robust to geometric distortions Such as rotation, translation and uniform scaling. After proper positioning and alignment of the 3D models, a watermark is embedded in the vertices of the model using a robust technique for modifying imperceptibly the location of a Subset of the 3D model vertices. The watermark can be used as a link to an identifier for the 3D model and the entire system can be used for data hiding applications. One application is the use of watermark as a link to 3D model descriptors for content-based search and retrieval. Experimental results show the ability of the proposed method to aforementioned attacks. The proposed method is also robust against vertex reordering attack.
