Pan-sharpening via High-pass Modification Convolutional Neural Network

1 code implementation24 May 2021 JiaMing Wang, Zhenfeng Shao, Xiao Huang, Tao Lu, Ruiqian Zhang, Jiayi Ma

Most existing deep learning-based pan-sharpening methods have several widely recognized issues, such as spectral distortion and insufficient spatial texture enhancement, we propose a novel pan-sharpening convolutional neural network based on a high-pass modification block.

Unsupervised Remote Sensing Super-Resolution via Migration Image Prior

1 code implementation8 May 2021 JiaMing Wang, Zhenfeng Shao, Tao Lu, Xiao Huang, Ruiqian Zhang, Yu Wang

Despite their success, however, low/high spatial resolution pairs are usually difficult to obtain in satellites with a high temporal resolution, making such approaches in SR impractical to use.

Region Convolutional Features for Multi-Label Remote Sensing Image Retrieval

no code implementations23 Jul 2018 Weixun Zhou, Xueqing Deng, Zhenfeng Shao

In our approach, we first train a FCN model using a pixel-wise labeled dataset, and the trained FCN is then used to predict the segmentation maps of each image in the considered archive.

PatternNet: A Benchmark Dataset for Performance Evaluation of Remote Sensing Image Retrieval

no code implementations11 Jun 2017 Weixun Zhou, Shawn Newsam, Congmin Li, Zhenfeng Shao

Current benchmark datasets are deficient in that 1) they were originally collected for land use/land cover classification and not image retrieval, 2) they are relatively small in terms of the number of classes as well the number of sample images per class, and 3) the retrieval performance has saturated.
