Parity enhanced topology based spot area watermarking method for copyright protection of layered 3D triangular mesh data

Abstract

A parity enhanced topology based spot area watermarking method is proposed to embed information in objects with layered 3D triangular meshes such as those reconstructed from CT or MRI data. With the integration of parity checking, it improves the robustness against unauthorized alteration of a single bit in every consecutive 8-bits of length. Watermark… (More)
