Title: Locally Adaptive Kernel Regression: A non-Parametric Framework for Visual Signal Processing and Recognition
Abstract:
I will present a non-parametric framework based on the notion of Kernel
Regression which we generalize to adapt to local characteristics of the given
data, resulting in descriptors which take into account both the spatial density
of the samples ("the geometry"), and the actual values of those samples ("the
radiometry"). These descriptors are exceedingly robust in capturing the
underlying structure of the visual signals even in the presence of significant
noise, missing data, and other disturbances. As the framework does not rely upon
strong assumptions about noise or signal models, it is applicable to a wide
variety of problems. On the processing side, I will illustrate examples in two
and three dimensions including state of the art denoising and upscaling. On the
vision side, I will describe the novel application of the framework to object
and action detection/recognition in images, and in video, respectively, from a
single example.
Bio:
Peyman Milanfar received the B.S. degree in electrical engineering/mathematics
from the University of California, Berkeley, in 1988, and the S.M., and Ph.D.
degrees in electrical engineering from the Massachusetts Institute of
Technology, Cambridge, in 1990, and 1993, respectively. Until 1999, he was a
Senior Research Engineer at SRI International, Menlo Park, CA. He is currently
Professor of electrical engineering at the University of California, Santa Cruz.
He was a Consulting Assistant Professor of computer science at Stanford
University, from 1998--2000, and a visiting Associate Professor there in 2002.
His technical interests are in statistical signal and image processing, and
inverse problems. Prof. Milanfar won a National Science Foundation CAREER award
in 2000. He is an Associate Editor of the IEEE TRANSACTIONS ON IMAGE PROCESSING
and was an Associate Editor for the IEEE SIGNAL PROCESSING LETTERS from 1998 to
2001. He is a member of the Signal Processing Society's Image, Video and
Multidimensional Signal Processing (IVMSP) Technical Committee.
