Comparative Study of Segmentation Algorithms for FLIR Images

摘要

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. (Author)
