Vladimir Kim will present his research seminar/general exam on Friday May 7

at 10AM in Room 302 (note room!).  The members of his committee are:

Tom Funkhouser (advisor), Adam Finkelstein, and Bernard Chazelle.  His

abstract and reading list follow below.  Everyone is invited to attend his talk,

and those faculty wishing to remain for the oral exam following are welcome to

do so.

Abstract:

I present a framework for symmetry-guided texture synthesis

and processing.  It is motivated by the long-standing problem of how

to optimize, transfer, and control the spatial patterns in textures.

The key idea is that symmetry representations that measure

autocorrelations with respect to all transformations of a group are a

natural way to describe spatial patterns in many real-world textures.

To leverage this idea, we provide methods to transfer 

symmetry representations from one texture to another, process

the symmetries of a texture, and optimize textures with respect to

properties of their symmetry representations.  These methods are

automatic and robust, as they don't require explicit detection of

discrete symmetries.  Applications are investigated for

optimizing, processing and transferring symmetries and textures.
