Recently there has been a growing interest in organizing systematic evaluations to compare the various techniques. Unfortunately the lack of common metrics for measuring the performance of multiple object trackers still makes it hard to compare their results. In this work we introduce two intuitive and general metrics to allow for objective comparison of tracker characteristics focusing on their precision in estimating object locations their accuracy in recognizing object configurations and their ability to consistently label objects over time. These metrics have been extensively used in two large-scale international evaluations the 2006 and 2007 CLEAR evaluations to measure and compare the performance of multiple object trackers for a wide variety of tracking tasks. Selected performance results are presented and the advantages and drawbacks of the presented metrics are discussed based on the experience gained during the evaluations. Copyright 2008 K.
