Fusion in image processing: specific features and digital approaches

In this article, we take a broad view of the term "information". In particular, it covers both data (e.g. measurements, images, signals, etc.) and knowledge (about data, about the domain, about constraints, etc.), which can be generic or specific.

• The definition of information fusion that we will use throughout this article is as follows:
