Paper Abstract

Multitarget tracking in cluttered environments has to deal with noisy measurements from ambiguous origins, which leads to a process of hypotheses generation and evaluation in addition to the traditional estimation problem. The multiple hypothesis tracking (MHT) algorithm is a statistical data association that provides a high level of support for false alarms and temporary occlusion at the cost of high processing requirements. This paper describes a methodology developed for the detection of moving and stationary point targets that feeds the MHT based tracking algorithm implemented. The time filtering approach developed for target detection is based on a combined spatio-temporal analysis approach optimized for clutter driven situations. The analysis of the local variance behavior within a time window is followed by a spatial processing stage based on motion segmentation by region growing. Moving regions presenting similar properties are thus clustered into single entities. Furthermore, a background estimation algorithm is also used, aiming to increase the robustness of the detection method. Multitarget tracking is then achieved through a MHT methodology based on the spatial features of the segmented motion regions. Special attention is given to the evaluation of performance of the method in real IR image sequences.
