TL;DR:
A new benchmark data set consisting of images from two widely used and publicly available satellite images, Landsat-8 and Sentinel-2, and a new multi-stream deep residual network (MDRN) fills an important gap in the existing benchmark datasets, which allows exploitation of multi-resolution spectral information from the cloud-free regions of temporally nearby images.

For more than five decades, remote sensing imagery has been providing critical information for many applications such as crop monitoring, disaster assessment, and urban planning. Unfortunately, more than 50% of optical remote sensing images are contaminated by clouds severely affecting the object identification. However, thanks to recent advances in remote sensing instruments and increase in number of operational satellites, we now have petabytes of multi-sensor observations covering the globe. Historically cloud imputation techniques were designed for single sensor images, thus existing benchmarks were mostly limited to single sensor images, which precludes design and validation of cloud imputation techniques on multi-sensor data. In this paper, we introduce a new benchmark data set consisting of images from two widely used and publicly available satellite images, Landsat-8 and Sentinel-2, and a new multi-stream deep residual network (MDRN). This newly introduced benchmark dataset fills an important gap in the existing benchmark datasets, which allows exploitation of multi-resolution spectral information from the cloud-free regions of temporally nearby images, and the MDRN algorithm addresses imputation using the multi-resolution data. Both quantitative and qualitative experiments show that the utility of our benchmark dataset and as well as efficacy of our MDRN architecture in cloud imputation. The MDRN outperforms the closest competing method by 14.1%.
