Title:  Multiscale Image Segmentation and Shape Analysis
Abstract: 
Image understanding necessarily includes two consecutive steps that can
serve as the basis for many higher level tasks such as object
recognition. The first is segmenting images into coherent
regions/objects, and the second is analyzing the shape of such regions.
In this talk I will present novel methods to tackle both these tasks.
First I will introduce segmentation by weighted aggregation (SWA), an
adaptive multiscale method for highly efficient extraction of coherent
regions, producing a full hierarchy of salient image parts. This
algorithm is inspired by algebraic multigrid theory, and was developed
with Ronen Basri and Achi Brandt in the Weizmann Institute of Science.
Second I will introduce the construction of a metric space of shapes,
allowing their classification by unique best deformations between
shapes. This shape space is constructed using conformal mapping theory,
and is a joint work with David Mumford in Brown University.
