A steganalytic algorithm for 3D polygonal meshes [PDF]
2014 IEEE International Conference on Image Processing (ICIP), 2014 We propose a steganalytic algorithm for watermarks embedded by Cho et al.'s mean-based algorithm [1]. The main observation is that while in a clean model the means of Cho et al.'s normalized histogram bins are expected to follow a Gaussian distribution, in a marked model their distribution will be bimodal. The proposed algorithm estimates the number of

A Galerkin boundary element method for high frequency scattering by convex polygons [PDF]
, 2007 In this paper we consider the problem of time-harmonic acoustic scattering in two dimensions by convex polygons. Standard boundary or finite element methods for acoustic scattering problems have a computational cost that grows at least linearly as a ...

3D Polygon Mesh Compression with Multi Layer Feed Forward Neural Networks [PDF]
Journal of Systemics, Cybernetics and Informatics, 2003 In this paper, an experiment is conducted which proves that multi layer feed forward neural networks are capable of compressing 3D polygon meshes. Our compression method not only preserves the initial accuracy of the represented object but also enhances ...

An automatic mesh generator for coupled 1D–2D hydrodynamic models [PDF]
Geoscientific Model DevelopmentTwo-dimensional (2D), depth-averaged shallow water equation (SWE) models are routinely used to simulate flooding in coastal areas – areas that often include vast networks of channels and flood-control topographic features and/or structures, such as ...
