Image decomposition into structure and texture subcomponents with multifrequency modulation constraints
Texture information in images is coupled with geometric macrostructures and piecewise-smooth intensity variations. Decomposing an image f into a geometric structure component u an...

The sum-of-increments constraint in the consecutive-ones matrix decomposition problem
The combinatorial problem of decomposing an integer matrix into a small positive linear combination of binary matrices that have the consecutive-ones property arises in cancer rad...

Modeling Virus Self-Assembly Pathways: Avoiding Dynamics Using Geometric Constraint Decomposition
We develop a model for elucidating the assembly pathways by which an icosahedral viral shell forms from 60 identical constituent protein monomers. This poorly understood process a...

Computing and Exploiting Tree-Decompositions for Solving Constraint Networks
Methods exploiting tree-decompositions seem to provide the best approach for solving constraint networks w.r.t. the theoretical time complexity. However, they have not shown a real...
