Research
I'm interested in video processing, image analysis, and related
applications of information theory.
I'm presently working on spatio-temporal
smoothness based motion compensated frame rate upconversion.
My previous
work was on: MAP based Superresolution. I tried to improve the performance of
the prior model by using relevant image statistics.
My presentation on
my preliminary work the same topic (on 25th Feb, 2006 in the Video Processing
Lab) can be found here.
I spent the summer of 2006 in NVIDIA Corp working on algorithms for image resolution enhancement.
Previous work
- Information theoritical analysis of
the print-scan channel model
I worked as an intern for 6 months in
HP Labs India, from Jan - July 2005.. My
guides were Dr. Shekar Borgaonkar, Director, Affordable Access Devices Group,
and research scientist Dr. Prasenjit Dey. My other collaborator was
Kishor Kr. Barman, who now works for HP
Labs India. We looked at the problem of modeling the information on paper which
passes through the printer and scanner The noisy print scan model as its
own set of issues to be dealt with, and we were able to address some of them.
Specifically, we also came up with a working demo for the verification of
printed documents using a normal scanner, based on a robust large scale
information hiding scheme.

Efficient video coding using the 3 dimensional DCT
I undertook this project when I was in
BITS, Pilani, India. By exploiting the
structure present in the 3D DCT, a new fast and memory efficient coding
scheme was proposed.
Prof.
Tripathi and
Prof. R. C.
Jain were the other contributors to this project. This work resulted in the
following paper:
Vikas
R, Shikha
Tripathi and R.C. Jain, “An
efficient real time low bit rate video codec”, 7th Asian
Conference on Computer Vision (ACCV) -2006, ,
IIIT, Hyderabad,India. Jan.,
13-16, 2006. (Published in Springer Lecture Notes on Computer
Science pdf)
- Audio processing on the ADSP
Blackfin
During the summer of 2004, I was awarded the (sought
after) engineering fellowship (YEFP) by Indian Institute of Science
(IISc) , Bangalore, India. I worked
under the guidance of Prof. .Mathias, in his DSP lab in the Sophisticated
Instruments Facility (SIF) . My work.
among other stuff, mainly involved the development of an MPEG compliant
audio codec on the Analog Devices BlackFin processor platform.
During my undergraduate days (which seems
like a long time ago), I was also actively involved in a project on Optical
Network modeling. We published some results in Elsevier Journal of Optic Fiber
Technology (
pdf)
based on our probabilistic analysis of call connection probability and node/link
failure for a few network topologies. Im presently not involved in this
area. However,
Prof.Chaubey
of BITS, Pilani, still does work on related (optical) issues, and my friend
S. Sen (in U.Penn) is researching
on the network design aspects.
I will be adding these links soon:
- Miscellaneous research elsewhere which I find interesting (not
necessarily in video).
- Fun stuff.
