Pansharpening refers to the problem of fusing a multispectral (MS) image and a panchromatic image in order to get an MS image at a finer spatial resolution than the one of the original MS image. Due to the lack of a reference image, the assessment of the quality of a pansharpened product is a challenging task. Typical solutions are related to the reduced resolution assessment by exploiting Wald's protocol or to indexes without reference. In this letter, an efficient approach based on the combination of the two above-mentioned solutions is proposed. The performance is assessed using real data acquired by sensors with very different features mounted on-board of the Pléiades, the WorldView-3, and the WorldView-4 satellite platforms.

Abstract
Pansharpening refers to the problem of fusing a multispectral (MS) image and a panchromatic image in order to get an MS image at a finer spatial resolution than the one of the original MS image. Due to the lack of a reference image, the assessment of the quality of a pansharpened product is a challenging task. Typical solutions are related to the reduced resolution assessment by exploiting Wald's protocol or to indexes without reference. In this letter, an efficient approach based on the combination of the two above-mentioned solutions is proposed. The performance is assessed using real data acquired by sensors with very different features mounted on-board of the Pléiades, the WorldView-3, and the WorldView-4 satellite platforms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
