Stan Birchfield is an associate professor in the Electrical and Computer Engineering Department of Clemson University. He received an M.S. and Ph.D. from Stanford University in 1996 and 1999, respectively, and a B.S. (with honors) from Clemson University in 1993, all in Electrical Engineering. While at Stanford, his research was supported by a National Science Foundation Graduate Research Fellowship, and he was part of the team that won first place at the AAAI Mobile Robotics Competition of 1994.  From 1999 to 2003 he was a research engineer with Quindi Corporation, a startup company in Palo Alto, California, where he developed algorithms for intelligent audio and video and was the lead engineer and principal architect of the Meeting Companion product. His experience in software engineering has led him to develop and maintain open-source computer vision software, such as the Kanade-Lucas-Tomasi (KLT) feature tracker. Over the years he has worked with or consulted for various companies, including Sun Microsystems, SRI International, Canon Research Center, and Autodesk.  His research interests are in computer vision, stereo correspondence, visual tracking, microphone array calibration, acoustic localization, and mobile robot navigation.
