FRG Workshop on Geometric Methods for Analyzing Discrete Shapes

Harvard University, May 7-9 (Friday-Sunday), 2021 virtually on Zoom

Overview:

The aim of the workshop is to bring together a community of researchers in mathematics, computer science and data sciences who develop theoretical and computational models to characterize shapes and analysis of image data.

This workshop is part of the NSF FRG project: Geometric and Topological Methods for Analyzing Shapes.

The first half of the workshop will feature talks aimed at graduate students, newcomers and a broad spectrum of audiences. Christopher Bishop (Stony Brook) and Keenan Crane (Carnegie Mellon) will each give two featured talks. The remaining part will have both background and research talks. There will also be organized discussions of open problems and potential applications.

Registration:

Registration is free and open to everyone. The link for the registration could be found in:
