Short biography

Christian ScharfenbergerI was a post-doctoral fellow in the Vision and Image Processing Lab from 10/2011-12/2014. I collaborated with the professors David Clausi, Alexander Wong, John Zelek, and Steven Waslander in the areas of image processing, computer vision, and robotics. Please find a selection of research projects I am/was involved with listed below.

Supervisors

 Alexander Wong, David A. Clausi

Research interests

My research interests are in the fields of computer vision, image processing, and pattern recognition with an emphasis on saliency computation, camera calibration and stereo vision. I am particularly interested in practical applications of computer vision and image processing methods to problems in robotics and driver assistance systems.
