Speakers:

Xavier Orriols from Barcelona is visiting us over the summer and working on some vision problems relevant to our Digital Archaeology project. Xavier will be at the SHAPE lab until the end of August.

Andrew Willis started his PhD studies last year at Brown, under the supervision of Prof. David Cooper.

Abstract

The idea is to find the sufficient statistics of axially symmetric objects via the analysis of latent space structure and Maximum Likelihood Estimation. Given a 3D dataset which represents a partial surface patch of a larger symmetric object, we attempt to estimate the axis of symmetry and the associated profile curve.

The formulation is developed in general terms and finally is specified to the axial symmetry problem as a demonstration of the different constraints that motivate the latent space structure. To this end, both parametric and non-parametric avenues of estimation are explored and evaluated for their strengths and weaknesses.

 

Work in collaboration with Prof. D. Cooper.
