In this seminar we will present an overview of the on-going research being performed at LEMS and in co-operation with others. In particular, we will describe recent efforts on some (or all, if time permits) of the following topics:

Introduction :

• Short presentation of Brown University, LEMS and the city of Providence.
• Brief presentation of the Faculty at LEMS, their main topics of research interests.
• Brief summary of existing collaborations within the Brown community and abroad.
• Brief summary of my own vitae and research interests.

3D Reconstruction :

• Free-form reconstruction through the use of implicit polynomial surface models
• 2D & 3D Medical Imaging reconstruction from 2D slices.
• 2D & 3D reconstruction using evolving surface models (bubbles).

2D & 3D Shape Representation :

• Representations of 2D and 3D datasets based on symmetry sets, for the characterization of shape parts, dynamics and evolution.
• Computational aspects in 2D and 3D :
  • retrieval of shocks in pure reaction or mixed diffusion-reaction evolution processes.
• Applications.

Image & 3D Object Database Management :

• Query by Sketch in image DB, by outline/example in silhouette DB.
• Query by Parts and Shape structure.

Graphics Applications :

• 2D shape morphing and genesis
• Interactive 3D rendering through Global Visibility computation
• Interactive 3D sketching

Multimedia Applications :

• CyberCity and CyberMonument
• Petra project (archaeology)

Conclusion :

• Potential for further collaborations & exchanges
