Super-resolving multiresolution images with band-independant geometry of multispectral pixels [article]

Nicolas Brodu
2017 arXiv   pre-print
A new resolution enhancement method is presented for multispectral and multi-resolution images, such as these provided by the Sentinel-2 satellites.  ...  This model is then applied to unmix low-resolution bands, preserving their reflectance, while propagating band-independent information to preserve the sub-pixel details.  ...  The algorithm is however generic and could be applied to other multi-resolution and multispectral satellite images.  ...
