Fusion in image processing: specific features and digital approaches

In digital fusion for image processing, efforts in recent years have led to a better understanding of the various theories from other fields, such as belief functions and fuzziness. We now know the right frameworks for applying these theories, their strengths and limitations in image processing, how to represent and model digital, symbolic or structural information and data in each of these formalisms, and how to combine them.
