In this study, a detailed performance comparison of standard and recent pansharpening approaches for GOKTURK-2 satellite images is presented. The Wald's Protocol was adopted in the experimental analysis, and Modulation Transfer Function (MTF) and Spectral Response Function (SRF) values of the GOKTURK-2 satellite were used for the first time in the literature for this purpose. By this means, the synthetic multispectral and panchromatic images were obtained realistically from GOKTURK-2 satellite images and the pansharpened results obtained with pansharpening methods were compared with the original images consistently. Quantatitave and visual results over multiple GOKTURK-2 images have shown that recent multi-resolution analysis methods provide better performance than standard component substitution methods and the most recent methods which use a priori knowledge about the satellite provide best pansharpening performance as expected.
