Abstract

In this paper a non-linear parabolic PDE-based diffusion model is applied to enhance thermal images. The proposed smoothing technique is a non-linear time-variant system, in which the diffusivity field depends on the local characteristics of the image. The non-linear diffusion is controlled by human knowledge based linguistic rules. Some examples of intensity dependent diffusion, of edge preserving filters and their aggregates are presented. The image details in the interested regions are preserved while in other regions the variations of pixel intensities are attenuated. With the proposed fuzzy-technique a strongly non-linear diffusivity function can be defined in a user-friendly way.
