-Bridge: A Look-Parametric Diffusion Bridge
Xuran Hu, Yujie Zhu, Tengxi Wang +2
Multiplicative Gamma noise is a signal-dependent degradation in coherent imaging; synthetic aperture radar (SAR) despeckling is its most prominent real-world instance. Existing dif…
SAR Despeckling via Region-Aware Sparse Representation and Statistical Noise Approximation
Xuran Hu, Mingzhe Zhu, Djordje StankoviÄ +3
Synthetic Aperture Radar (SAR) imagery are widely utilized in remote sensing due to their all-weather, all-day imaging capabilities. However, SAR images are highly susceptible to n…
GeoHeight-Bench: Towards Height-Aware Multimodal Reasoning in Remote Sensing
Xuran Hu, Zhitong Xiong, Zhongcheng Hong +3
Current Large Multimodal Models (LMMs) in Earth Observation typically neglect the critical "vertical" dimension, limiting their reasoning capabilities in complex remote sensing geo…
Perturbation on Feature Coalition: Towards Interpretable Deep Neural Networks
Xuran Hu, Mingzhe Zhu, Zhenpeng Feng +2
The inherent "black box" nature of deep neural networks (DNNs) compromises their transparency and reliability. Recently, explainable AI (XAI) has garnered increasing attention from…
Multi-task SAR Image Processing via GAN-based Unsupervised Manipulation
Xuran Hu, Mingzhe Zhu, Ziqiang Xu +2
Generative Adversarial Networks (GANs) have shown tremendous potential in synthesizing a large number of realistic SAR images by learning patterns in the data distribution. Some GA…
