Detection of tripwires using diffusion

摘要

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.
