DeepSent – Deep Learning-Based Multiple-Image Super-Resolution for Sentinel-2 Data

KP Labs Sp. z o.o. (PL)


The aim of the activity is to apply super-resolution reconstruction multispectral Sentinel-2 images, using multiple images of the same region, captured at different points in time (MISR, multiple-image super-resolution). This is achieved by adapting recent deep neural networks that were recently proposed for dealing with MISR, to the particularities of Sentinel-2 data. In particular the project focusses on three aspects: adapting the existing networks to process multispectral images, proposing techniques for preparing the training data, and selecting and pre-processing the input low-resolution data. The existing networks are applied to super-resolve the Sentinel-2 images in a band-wise manner (each band treated independently), followed by exploiting the correlation among the multiple bands. The output contains a panchromatic image, as well as an RGB/multispectral image of higher resolution than the one presented at the input.
