Identifying every building's function in large-scale urban areas with multi-modality remote-sensing data

no code implementations8 May 2024 Zhuohong Li, wei he, Jiepan Li, Hongyan zhang

In this study, we proposed a semi-supervised framework to identify every building's function in large-scale urban areas with multi-modality remote-sensing data.

Generalized Few-Shot Meets Remote Sensing: Discovering Novel Classes in Land Cover Mapping via Hybrid Semantic Segmentation Framework

1 code implementation19 Apr 2024 Zhuohong Li, Fangxiao Lu, Jiaqi Zou, Lei Hu, Hongyan zhang

Land-cover mapping is one of the vital applications in Earth observation, aiming at classifying each pixel's land-cover type of remote-sensing images.

Degradation-Noise-Aware Deep Unfolding Transformer for Hyperspectral Image Denoising

no code implementations6 May 2023 Haijin Zeng, JieZhang Cao, Kai Feng, Shaoguang Huang, Hongyan zhang, Hiep Luong, Wilfried Philips

However, model-based approaches rely on hand-crafted priors and hyperparameters, while learning-based methods are incapable of estimating the inherent degradation patterns and noise distributions in the imaging procedure, which could inform supervised learning.
