Smoothing and Adaptive Redistribution for Grids with Irregular Valence and Hanging Nodes
We describe some extensions to the grid smoothing scheme described in [1, 2] that deal with the following issues: 1) the clustering effect of changing valence in an unstructured ...

Heat kernel smoothing on unit sphere
In brain imaging, cortical data such as the cortical thickness, cortical surface curvatures and surface coordinates have been mapped to a unit sphere for the purpose of visualizat...

Parsing Silhouettes without Boundary Curvature
We describe a new decomposition algorithm for twodimensional, polygonal shapes. The algorithm first finds a set of overlapping ribbon-like subshapes ("ribbons") by group...

Detection of LSB Steganography based on Image Smoothness
The detection of LSB steganography is a question of common interest in the research of steganalysis techniques. In this paper, the distribution of the difference between the curre...
