Multimodal Large Language Models for Remote Sensing Image Understanding: Domain-Specific or General-Purpose?

Qiwei Ma, Chunping Qiu, Xinjun Cheng, Xiaoyu Zhang, Puhong Duan, Ke Yang, et al.

The rapid development of multimodal large language models (MLLMs) has introduced a flexible paradigm for remote sensing image scene understanding (RSISU), enabling natural-language interaction with remote sensing imagery. However, a systematic understanding of the capability boun…

Not All Patches are Equal: Sampling Matters for Visible-Infrared Pre-Training

Qiwei Ma, Bin Deng, Junjie Zhu, Qiangjuan Huang, Puhong Duan, Ke Yang, et al.

Visible-infrared (VIS-IR) alignment is a key pre-training task for robust multi-sensor perception. Most existing methods use uniform patch-wise contrastive learning, but this can be unreliable in VIS-IR data because imaging-physics differences make some spatially paired regions i…
