About me
I am now a happily graduated PhD student in the GRASP Lab at UPenn, and my advisor is Dr C.J.Taylor. My
primary research area
is Computer Vision. In particular, the usage of convex optimization techniques such as interior point methods to solve certain classes of energy
minimization problems.
Before I began life at Penn, I
got my M.S at IIT
Delhi
in
Mathematics and Computing.
PhD Thesis
My PhD thesis is on the application of certain ideas from Convex Optimization for Energy Minimization problems in
Computer Vision. I recently defended my thesis and here are the slides.

Research Projects
The research in the thesis can be divided into two projects
Graph cuts using L1 norm minimization
The standard min-cut problem is reduced to an unconstrained L1 norm minimization which in turn is reduced to a linear program.
The linear program is solved using parallel architecture. We presented
a poster at the Penn Research Symposium on this topic
[
ppt].
We have a slightly out of date technical paper on the topic which can be
found at scholarly
commons.
The current results will appear in a future edition of PAMI,
the preprint version is online at the moment and can also be found here pamipaper
The usage of a GPU to solve general purpose problems is currently a big area of research.GPGPU.org contains
tons of information and a very active forum.
Stereo
Using the ideas developed during the course of our work on Graph cuts, we create a convex approximation to an energy function for stereo problems.
Our 3DPVT 2008 paper discusses this in greater detail. 3dpvtpaper.
Teaching
My greatest joy during my PhD years was teaching and I took every opportunity I had to teach and interact with students.
-
Currently, Spring 2008, I am teaching ESE220, an undergraduate course on Data Structures and Algorithms.
-
Teaching assistant for undergraduate calculus (MATH 103, Fall 2006). Handled 4 sets of recitations each comprising
a group of around 10 students.
-
Teaching assistant for undergraduate discrete mathematics (CSE 260, Fall 2005). Handled recitations for a group
of around 15 students.
-
Teaching assistant for graduate theory of computation (CIS 511, Spring 2004).
-
Teaching assistant for undergraduate computer architecture (CSE 240, Fall 2003).
I also answered queries at goiit.com an online forum for preparation for the Joint Entrance Examination. The Joint Entrance Examination is the entrance test for the Indian Institutes of Technology, India's premier technical institutes.
Work Experience
Internship
Interned at CLIPS-IMAG during Summer 2001 under Dr Georges
Quenot and worked on reliable feature point extraction for Dr Quenot's project on motion recovery from video.
