CORRECTION: Elena Sizikova will present her Generals on 4/30/15 at 9am in CS 402 (notice - date change)

Elena Sizikova will present her Generals on 4/30/15 at 9am in CS 402.

The members of her committee are: Tom Funkhouser (adviser), Adam Finkelstein, and Mona Singh. Everyone is invited to attend her talk, and those faculty wishing to remain for the oral exam following are welcome to do so.  Her abstract and reading list follow below.

Many problems in computer graphics require processing sets of partially wrong pairwise measurements to find a globally optimal arrangement. One such example arises from research on reconstruction of ancient Theran frescos, in which scans of partially eroded fragments were obtained in an effort to automate the reconstruction process. Previously, algorithms were developed to propose potential pairwise matches between adjacent fragments, but the majority of the resulting matches are false predictions. In this work, I explore a genetic algorithm based approach that includes a robust global relaxation step to both recover clusters of correctly and consistently aligned fragments
and to detect and discard predicted matches that are false.
