Abstract

Profiling sensor systems have been shown to be effective for detecting and classifying humans against animals. A profiling sensor with a 360 horizontal field of view was used to generate profiles of humans and animals for classification. The sensor system contains a long wave infrared camera focused on a smooth conical mirror to provide a 360 degree field of view. Human and animal targets were detected at 30 meters and an approximate height to width ratio was extracted for each target. Targets were tracked for multiple frames in order to segment targets from background. The average height to width ratio was used as a single feature for classification. The Mahalanobis distance was calculated for each target in the single feature space to provide classification results.
