Abstract: The evaluation of the spatial quality is one of the factors that determine the performance of pansharpening algorithms for remote sensing images. However, the number of studies that focus on the functioning of these measures is not extensive. This paper addresses the evaluation of the performance of spatial assessments of pansharpened images. For this, a test of affine transformations that distorts the image used as reference is designed and implemented. This test is applied to the images of a database created for this purpose. Thus the behavior of different selected spatial indices is obtained. As well as the results of a proposed new spatial index based on the discrete cosine transform. Additionally, spatial quality measurements have been carried out between the panchromatic and pansharpened images in order to test the performance of the spatial quality indices.
