A Conditional Generative Adversarial Network to Fuse Sar And Multispectral Optical Data For Cloud Removal From Sentinel-2 Images

no code implementations IGARSS 2018 Claas Grohnfeldt, Michael Schmitt, Xiaoxiang Zhu

In this paper, we present the first conditional generative adversarial network (cGAN) architecture that is specifically designed to fuse synthetic aperture radar (SAR) and optical multi-spectral (MS) image data to generate cloud- and haze-free MS optical data from a cloud-corrupted MS input and an auxiliary SAR image.

Joint & Progressive Learning from High-Dimensional Data for Multi-Label Classification

no code implementations ECCV 2018 Danfeng Hong, Naoto Yokoya, Jian Xu, Xiaoxiang Zhu

Despite the fact that nonlinear subspace learning techniques (e. g. manifold learning) have successfully applied to data representation, there is still room for improvement in explainability (explicit mapping), generalization (out-of-samples), and cost-effectiveness (linearization).
