There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
----------------
The proposed thesis focuses on providing definitions, closed-form expressions and algorithmic solutions for computing averages of sets of shapes and associated standard deviation fields. By shapes, we mean lines, planes, curves, and surfaces. Note that these shapes are situated, a term by which we mean that their scales, orientations, and positions are fixed and important.
We establish sufficient conditions on sets of shapes for which our proposed solutions
yield topologically valid results, and call such sets compatible. We propose, study and apply suitable generalizations of the statistical formulations of the average and standard deviation of sets of numbers to sets of compatible shapes. In particular, the solutions proposed extend naturally the popular concept of the medial axis to two and more curves in the plane or in three-dimensions and to two or more surfaces.
