Spectral Imaging of Matisse's Pot of Geraniums: A Case Study
The accuracy of color image-acquisition systems is most often evaluated using test targets of uniform color patches imaged under optimal conditions. In artwork imaging, system per...

On the set multi-cover problem in geometric settings
We consider the set multi-cover problem in geometric settings. Given a set of points P and a collection of geometric shapes (or sets) F, we wish to nd a minimum cardinality subse...

Audiovisual-to-articulatory speech inversion using Active Appearance Models for the face and Hidden Markov Models for the dynami
We are interested in recovering aspects of vocal tract’s geometry and dynamics from auditory and visual speech cues. We approach the problem in a statistical framework based on ...
