Embedding in Two Least Significant Bits with Wet Paper Coding
In this paper, we present three embedding schemes for extensions of least significant bit overwriting to both of the two lowest bit planes in digital images. Our approaches are in...

HSN-PAM: Finding Hierarchical Probabilistic Groups from Large-Scale Networks
Real-world social networks are often hierarchical, reflecting the fact that some communities are composed of a few smaller, sub-communities. This paper describes a hierarchical B...

Non-Replicating Indexing for Out-Of-Core Processing of Semi-Regular Triangular Surface Meshes
We introduce an indexing scheme for the vertices of semi-regular meshes, based on interleaving quadtrees rooted on the edges of the base mesh. Using this indexing scheme we develo...
