Abstract : In this article a novel thinning algorithm based on time-reversed heat conduction model is proposed. The image is viewed as a thermal conductor and thinning task is then considered as a inverse process of heat conduction. Given an image, the direction map of heat conduction is first computed, then time-reversed heat conduction is simulated. The result turns out to be a thinned pattern. The algorithm can be applied to gray-scale or binary images.
