Assessment of the quality of fused products

Our work deals with the synthesis of multispectral images at a better spatial resolution by the means of another image having such a resolution. We show the lack of standard procedure to assess the expected benefits of fused products. We discuss the case of the reference that is missing in most cases. We discuss the principles of the assessment protocol. One principle is that the constructed synthetic images should be close to reality. The second principle is that the fused products should offer a strong consistency with the original data set. This results into two properties of the fused products. We propose a protocol that assesses the quality of fused products with respect to these properties. We define a general framework and the protocol is still open.
