Generalized Tree-Based Wavelet Transform
In this paper we propose a new wavelet transform applicable to functions defined on graphs, high dimensional data and networks. The proposed method generalizes the Haar-like transf...

Hierarchical Watermarking of Semiregular Meshes Based on Wavelet Transform
This paper presents a hierarchical watermarking framework for semiregular meshes. Three blind watermarks are inserted in a semiregular mesh with different purposes: a geometrically...
