Evaluation and Comparison of Optical Flow Techniques

Research Overview

In collaboration with John Barron and Steven Beauchemin (University of Western Ontario), I conducted an extensive performance analysis of well-known optical flow algorithms (circa 1993). With independent implementations and a common set of synthetic and natural inputs, we showed that the results of different methods differed significantly. Phase-based and gradient-based techniques produced the most reliable results over the input sequences we used. Our test suite and results, along with our implementations, have been available to others on the web since 1994, and they are used widely. They remain the benchmark against which new methods are judged.
