Abstract

In this paper, a method is proposed for the integration of information which can be derived from the thermal infrared and visual modes based on the use of edge (dissimilarity) properties of the two types of images. The method involves the use of the Sobel operator to extract and classify edge points according to their strengths. A point-by-point comparison of edges from the visual and TIR images is made. Heuristics, supported by the physical processes affecting the image formation, are employed to give a probabilistic interpretation to each point in the images based on the strengths of edge points detected in the two images at the point. The validity of this approach is tested in a laboratory environment.
