May 2014 Embedded Vision Summit Technical Presentation: "Embedded Lucas-Kanade Tracking: How It Works, How to Implement It, and How to Use It," Goksel Dedeoglu, PercepTonic
Goksel Dedeoglu, Ph.D., Founder and Lab Director of PercepTonic, presents the "Embedded Lucas-Kanade Tracking: How It Works, How to Implement It, and How to Use It" tutorial at the May 2014 Embedded Vision Summit.
This tutorial is intended for technical audiences interested in learning about the Lucas-Kanade (LK) tracker, also known as the Kanade-Lucas-Tomasi (KLT) tracker. Invented in the early 80s, this method has been widely used to estimate pixel motion between two consecutive frames.
Dedeoglu presents how the LK tracker works and discuss its advantages, limitations, and how to make it more robust and useful. Using DSP-optimized functions from TI's Vision Library (VLIB), he also shows how to detect feature points in real-time and track them from one frame to the next using the LK algorithm. He demonstrates this on Texas Instruments' C6678 Keystone DSP, where he detects and tracks thousands of Harris corner features in 1080p HD resolution video.
