Shape Analysis Research Project

Summary:

The main focuses of Shape Analysis Research Project (SARP) are to investigate 3D shape-based retrieval and to apply shape analysis to address a number of scientific research problems.

Description:

We have applied 3D shape-based retrieval to various disciplines such as computer vision, CAD/CAM, computer graphics, molecular biology and 3D anthropometry. We have organized two workshops on 3D shape retrieval and two shape retrieval contests. We also have developed 3D shape benchmarks, performance evaluation software and prototype 3D retrieval systems

We have developed a robotic map quality assessment tool in collaboration with MEL. We also have developed different shape descriptors to represent 3D human bodies and heads efficiently and other work related to 3D anthropometry. Finally, we also have done some in a Structural Bioinformatics, Bio-Image analysis and retrieval.

Additional Technical Details:

Organizing two 3D Shape Retrieval tracks: The two tracks are the Partial Shape Retrieval Track and the Generic Shape Retrieval Track, organized under the SHREC'09 - 3D Shape Retrieval Contest 2009 (http://www.aimatshape.net/event/SHREC/), and in the context of the EUROGRAPHICS 2009 Workshop On 3D Object Retrieval, 29 March 2009 http://3dor.ge.imati.cnr.it/About.html
