Collision detection of a Robotic Arm fitted with Microsoft Kinect wherein I programmed using CUDA ( Nvidia's GPU programming language ) and designed a parallel algorithm using techniques like hashing and harnessing CUDA's thrust libraries and 3D thread blocks.
Current affiliation: Software Developer at Apple Inc. in Cupertino, California, USA

Tazitdinov Ilya Tazitdinov PhD student
Development of parallel CUDA algorithm for collision detection. Different implementations of spatial hashing for fast collision detection for large number of objects.

DSouza Joy Winston D'Souza
Segmentation-Free Articulated Object Detection on the GPU - Implemented a real-time method for tracking hand poses through image sequences using a color divergence-based similarity measure on the massively parallel paradigm of the GPU. My work included adding improvements to an existing markerless real-time camera-based hand tracking system, such as a novel Multigrid hypotheses approach to hand-template matching and porting the system onto the GPU, using C++ along with the CUDA, CUDPP and Thrust libraries.
