Abstract
Various techniques are provided to combine visible and thermal image data. In one example, a method includes receiving visible image data and thermal image data for a scene. The method also includes extracting high spatial frequency content from the visible image data to provide filtered visible image data. The method also includes applying a corresponding gain to the filtered visible image data to provide weighted visible image data. The method also includes merging the weighted visible image data and the thermal image data to provide combined image data. Additional methods, systems, and other implementations are also provided.
