PA-Net: Precipitation-Adaptive Mixture-of-Experts for Long-Tail Rainfall Nowcasting
Xinyu Xiao, Sen Lei, Eryun Liu +5
Precipitation nowcasting is vital for flood warning, agricultural management, and emergency response, yet two bottlenecks persist: the prohibitive cost of modeling million-scale sp…
UniVid: Pyramid Diffusion Model for High Quality Video Generation
Xinyu Xiao, Binbin Yang, Tingtian Li +2
Diffusion-based text-to-video generation (T2V) or image-to-video (I2V) generation have emerged as a prominent research focus. However, there exists a challenge in integrating the t…
A Dual-Branch Framework for Semantic Change Detection with Boundary and Temporal Awareness
Yun-Cheng Li, Sen Lei, Heng-Chao Li +1
Semantic Change Detection (SCD) aims to detect and categorize land-cover changes from bi-temporal remote sensing images. Existing methods often suffer from blurred boundaries and i…
Mamba-MOC: A Multicategory Remote Object Counting via State Space Model
Peng Liu, Sen Lei, Heng-Chao Li
Multicategory remote object counting is a fundamental task in computer vision, aimed at accurately estimating the number of objects of various categories in remote images. Existing…
Exploring Generalizable Pre-training for Real-world Change Detection via Geometric Estimation
Yitao Zhao, Sen Lei, Nanqing Liu +3
As an essential procedure in earth observation system, change detection (CD) aims to reveal the spatial-temporal evolution of the observation regions. A key prerequisite for existi…
SAM-Based Building Change Detection with Distribution-Aware Fourier Adaptation and Edge-Constrained Warping
Yun-Cheng Li, Sen Lei, Yi-Tao Zhao +3
Building change detection remains challenging for urban development, disaster assessment, and military reconnaissance. While foundation models like Segment Anything Model (SAM) sho…
