Interests
Computer Vision
My current research interest lies in Computer Vision. I
am particularly interested in model-based tracking in video-sequences,
probabilistic methods for approximate inference, statistical methods and
machine learning techniques for detection and recognition, and multi-view
vision.
Humans are capable of understanding the world they see
with seemingly no effort. Yet computers are way far from such performance.
Being able to determine what objects are present in a scene in an image or
even whether a person is present in the scene is still a hard problem and is
a wide research topic. A more complex area of intense research that I
concentrate on is human
tracking. I am interested in estimating the 3D pose of the body of a person
in sequences of images.
I have developed software
that estimates human motion in images taken with multiple synchronized
cameras.
At Brown we have our own Motion Capture Lab where we can
capture motion data for evaluating the software.
Network Reliability Analysis
During my undergraduate studies at Lafayette College, I
have been working together with Lorenzo Traldi on analyzing network
reliability problems using symbolic logic.
