A Comparative Study of Segmentation Algorithms for FLIR Images

Abstract : A comparative study of FLIR segmentation algorithms has been conducted in cooperation with Westinghouse Defense Systems Division. In the Maryland portion of the study, four techniques (two and three-class relaxation, pyramid linking, and superspike) were tested on a Westinghouse-supplied database of 51 images obtained from NVL and other sources. (Two other techniques, superslice and pyramid sport detection, were rejected after preliminary studies. ) The best technique, superspike, extracted regions corresponding to over 88% of the targets, and had a false alarm rate of 1.6 false regions per true target.
