Abstract

We introduce a method for blind watermarking of three dimensional (3D) meshes based low-density parity check (LDPC) coded quantization index modulation (QIM). The 3D host vertex selection algorithm identifies vertices in rough concave regions of the surface that are invariant to mesh optimization/ simplification on which the QIM operates. The LDPC code recovers the runlength coded data hidden in the vertices deleted by mesh optimization and/or simplification. For a given bit-error rate performance of a recovered watermark, the proposed scheme permits storing much longer watermarks compared to the state of the art approaches.
