Tracker Analysis and Ground Truth Tool Description for the Proceedings of the 2002 Ground Target Modeling and Validation Conference
Abstract
The Tracker Analysis and Ground-Truth (TAG) tool was developed to streamline the process of defining a target region for each image in an image sequence in order to calculate signature metrics and perform tracker analysis. Previously. images within a sequence were analyzed individually by outlining the target in each image and calculating the relevant statistics. Likewise, tracker performance was determined by a man-in-the-loop viewing of tracker results overlaid on the image sequence. While effective, these methods did not allow the timely processing of long sequences and limited the calculation of signature metrics to only a few frames of a sequence. Using the TAG tool, a single rectangle is drawn around the at the beginning of the sequence. The rectangle is shifted and resized using mouse motion and target keystrokes as the sequence is played. The rectangle size and location is stored in a file which can be replayed and modified. This file can be used as input to SEMIRS (Software for Extracting Metrics from infrared Sequences) for generation of signature metrics for each image and as stabilization input to ISAT (infrared Seeker Algorithm Tool) which generates tracker output. The TAO tool has made it possible to generate, store, and utilize valuable ground truth information for entire sequences in a short period of time. This paper will focus on the utilization, functionality and application of the TAG tool.
