This paper introduces a method to extract 'Shape-DNA', a numerical fingerprint or signature,
of any 2d or 3d manifold (surface or solid) by taking the eigenvalues (ie the spectrum) of its …

This paper presents a robust watermarking algorithm with informed detection for 3D
polygonal meshes. The algorithm is based on our previous algorithm [22] that employs mesh …

Digital watermarking embeds a structure called watermark into the target data, such as
image and 3D polygonal models. The watermark can be used, for example, to enforce …

In this paper, we present a new scheme for digital steganography of three-dimensional (3-D)
triangle meshes. This scheme is robust against translation, rotation, and scaling operations …

We introduce dynamic watermarking techniques for protecting the value of intellectual
property of CAD and compilation tools and reusable design components. The essence of the …

This paper introduces a method to extract fingerprints of any surface or solid object by taking
the eigenvalues of its respective Laplace-Beltrami operator. Using an object's spectrum (ie …

In this paper, two novel methods suitable for blind 3D mesh object watermarking
applications are proposed. The first method is robust against 3D rotation, translation, and …

A new methodology for fingerprinting and watermarking three-dimensional (3-D) graphical
objects is proposed in this paper. The 3-D graphical objects are described by means of …

Designing a powerful fragile watermarking technique for authenticating three-dimensional (3-
D) polygonal meshes is a very difficult task. Yeo and Yeung were first to propose a fragile …

We fit the data for the binary lens microlensing event MACHO 98-SMC-1 from five different
microlensing collaborations and find two distinct solutions characterized by binary …
