Abstract
Autonomous detection of tripwires using optical systems is of great interest. This paper describes methods for detection of tripwires using an image processing algorithm based on the diffusion equation. A video camera with sensitivity in the near infrared (IR) band records the target scene and the digital images are then transported to a computer to apply an image processing algorithm to determine if a tripwire is present. In this paper, we show that coherence enhancing diffusion filtering can recover broken edges and smooth background without smoothing coherent structures. A comparison of detection results is given with and without diffusion filtering.
