Multiscale description of Sentinel-2/MAJA products: a spectral and structure function approach
Résumé
Sentinel-2 surface reflectances exhibit a strong spatial variability that is due to both natural variability and strong anthropogenic effects. From an image processing view point, Sentinel-2 products maybe seen as images that embed a hierarchy of spatial structures of different sizes and of different energy levels. Many remote-sensing images of natural variables show a fractal structure that can be evidenced by various geometrical and statistical tools. Thus, it is tempting to check if Sentinel-2 images exhibit such scaling features.The objective of this study is to test the existence of scaling properties in Sentinel-2/MAJA products based on two main tools: 2D Fourier power spectra and first order structure functions.
