“…Quality evaluations have been carried out at the full spatial scale (0.50 m for GeoEye-1 products) equal to that of the original Pan [51,52]. The check at full scale foresees separate measurement of spectral consistency, which may be defined according to Wald's protocol [53], and spatial consistency, which may be defined according to either QNR [54] or Khan's [55] protocol.…”

“…Despite of its accuracy (thanks to the presence of a reference image), the above-mentioned procedure is based on an implicit assumption of "invariance among scale" that could not be valid. For this reason, several protocols at full resolution, i.e., validating the fused products coming from the fusion of the original MS and PAN images, have been proposed in the literature [52][53][54][55][56][57]. In this work, the hybrid quality with no reference index (HQNR) [58] is selected.…”

“…QNR D  indicates that the inter-relation between the fused bands should be as identical as the relation between MS bands and QNR s D indicates that the relation between each fused band and PAN image should be identical to those between MS band and low resolution PAN. By combining these two distortions a unique quality index named QNR can be obtained (Alparone et al 2008), (Carlà et al 2015).…”

“…The foundation of this protocol is based on Wald's consistency property. This protocol uses the basis of Zhou's protocol (extracting high-pass information) to measure the spatial distortion and basis of QNR protocol to measure spectral distortion (Carlà et al 2015). In fact, Khan et al tried to improve the previous protocols by using the strengths of each of the aforementioned protocols.…”
