Missing Data Reconstruction in Remote Sensing image with a Unified Spatial-Temporal-Spectral Deep Convolutional Neural Network

1 code implementation23 Feb 2018 Qiang Zhang, Qiangqiang Yuan, Chao Zeng, Xinghua Li, Yancong Wei

Because of the internal malfunction of satellite sensors and poor atmospheric conditions such as thick cloud, the acquired remote sensing data often suffer from missing information, i. e., the data usability is greatly reduced.

Learning a Dilated Residual Network for SAR Image Despeckling

1 code implementation9 Sep 2017 Qiang Zhang, Qiangqiang Yuan, Jie Li, Zhen Yang, Xiaoshuang Ma

In this paper, to break the limit of the traditional linear models for synthetic aperture radar (SAR) image despeckling, we propose a novel deep learning approach by learning a non-linear end-to-end mapping between the noisy and clean SAR images with a dilated residual network (SAR-DRN).

Strategyproof Mechanisms for Additively Separable Hedonic Games and Fractional Hedonic Games

no code implementations27 Jun 2017 Michele Flammini, Gianpiero Monaco, Qiang Zhang

In this paper we consider strategyproof mechanisms for additively separable hedonic games and fractional hedonic games, that is, partitioning methods without payments such that utility maximizing agents have no incentive to lie about their true preferences.

Relative Hidden Markov Models for Evaluating Motion Skill

no code implementations CVPR 2013 Qiang Zhang, Baoxin Li

The proposed algorithm effectively learns a model from the training data so that the attribute under consideration is linked to the likelihood of the inputs under the learned model.
