In the 90s, Tracey worked for two years post-college for Xerox Desktop Document Systems (believed to have since become Nuance. There Tracey used her formal background and training in machine vision and image analysis to analyze the contents of documents in efforts to empower computers to understand the world of images in a manner similar to humans (for example Optical Character Recognition). Tracey was also their webmaster. She was inventor on four image analysis patents.
Tracey graduated from Cornell University with a Bachelor’s of Science in Computer Science and a Master’s of Engineering in Computer Science. She worked with mentor Dan Huttenlocher in the Computer Science Robotics and Vision Lab on problems in machine vision, like tracking moving objects with both stationary and (arbitrarily) moving cameras. She published two papers; one was accepted to a computer vision conference.
