Title
3D multiresolution synchronization scheme based on feature point selection
Abstract
Multimedia protection is one of the main research challenges in computer sciences.(1) We can encrypt the media in order to make the content unreadable without a secret key of decryption, protect the file with Digital Right Management (DRM), or embed an hidden message in the file (watermarking and steganography). We are interested in data hiding applications for 3D mesh. In this domain, there are various problems, of which the synchronization of the message in the support host. The synchronization is the operation that allows to scan a mesh with a unique path and by selecting the same areas (vertices, triangles, quadrangles, for example) before and after the embedding even if the mesh has been noised. In this paper, we propose a new synchronization approach based on feature point selection in a low resolution of the 3D object. The building of the low resolution is made by decimation(2) and the feature point selection is based on the discrete curvature computing. We evaluate the robustness of the synchronization in the low resolution and in the high resolution.
