Paper Abstract

Map data can provide contextual cues that enhance ATR system performance. Maps, however, sometimes lack scene cues such as secondary trails. In these instances, trail detection requires map-independent approaches. Therefore, we have developed a feature-based trail detection algorithm. Its low-level function extracts features (edges, lines) that characterize trail geometry. A high-level function evaluates scene features, ranks them according to their trail-like attributes, and applies rules. Rules interpret complicated scenarios such as partial trail occlusion and high trail curvature. The algorithm demonstrates robust performance on both FLIR and TV imagery.
