A note to students:
If you need me to sign something (e.g., a form for the examination office), please hand it to Tanja Rethemeyer (see below). You can later pick it up from her office.
If you would like to make an appointment for an oral exam (short or long), please send an email to Tanja Rethemeyer (see below).
If you need to talk to me about possible acknowledgment of credits, please come to my office hours and bring all relevant documents, transcripts, slide copies, forms, etc.
If you would like to enquire about possible thesis topics, please look at our research pages and the Thesis page, then come to me during my office hours, or talk to my PhD students, or talk to me right after lecture. You are welcome to suggest thesis topics of your own.
If you need to write me an email, please try to be concise.
If you have a question about my courses, it is probably easiest, if you give me a call during my office hours, or catch me right before or after any lecture.

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.
