RESEARCH EXPERIENCE

Graduate Student (External): Automated Molecular Imaging Group, The Scripps Research Institute, La Jolla, CA
01/2007 - 11/2007

Molecular Imaging & Reconstruction

• Developed an unsupervised classification algorithm to improve 3D reconstructions of protein macromolecules from extremely noisy digital images captured using an electron microscope. Several digital images of the molecule that have the same viewing parameters are averaged to improve the signal to noise ratio. We developed an automated algorithm to identify and reject images of molecules having inconsistent viewing parameters, or having extremely low signal to noise ratio.
• Developed an algorithm to estimate the astigmatism present in the micrographs captured using an electron microscope, using a RANdom SAmple Consensus (RANSAC)-based approach. When the astigmatism – a parameter in the contrast transfer function of an electron microscope – is not estimated and corrected for, the resolution of 3D reconstruction suffers significantly.
• Developed an expertise in pipeline-based automated processing of molecular imaging and reconstruction. It includes automated contrast enhancement of micrographs, automated particle picking and classification of particles, and 3D reconstruction of macromolecules.

Tools Used: Matlab, Python

Graduate Research Assistant: Computer Vision & Image Analysis Research Laboratory, USF 08/2003 - 12/2006

Video Analysis

• Developed an algorithm for American Sign Language (ASL) recognition by analyzing video sequences of an ASL signer. Unlike previous approaches, we do not require the signer to wear specialized colored gloves, and we do not need explicit tracking of the body parts.
• Developed a random sampling-based algorithm for capturing the shapes and spatial configurations of objects in an image using low-level primitives, e.g. edge points, and efficiently computing the histograms used for representing motion.
• Proposed a novel technique for embedding histograms into a low-dimensional space by preserving the probabilistic distances like Bhattacharya, Matusita, Chernoff, Kullback Leibler (KL) and symmetric-KL distance measures.
• Implemented the interpolation of motion sequences and empirically showed that it improves recognition accuracy.

Gesture Recognition and Human Activity Classification

• Developed a detection-based algorithm for gesture recognition and activity classification without performing tracking, and by using global pose changes instead. Showed results of the algorithm on public datasets.

Learning from Multiple Video Sequences

• Developed a probabilistic framework based on Iterated Conditional Modes to automatically learn individual signs from video sequences of continuous sign language sentences.

Tools Used: Matlab, C++

WORK EXPERIENCE

• Worked as a team member in the development of a web application for monitoring and updating inspection data of mobile houses collected using handheld devices. Client: GE-ModSpace, USA

Tools Used: Java Servlets, Oracle, PL/SQL

Undergraduate Intern: Software Technology Parks of India, Hyderabad, India
