Lightweight Adaptation of General-Purpose VLMs for Multispectral and SAR Image Understanding

General-purpose vision-language models (VLMs) now support strong visual recognition, instruction following, and generation. However, most pretrained visual encoders are built around three-channel natural images and do not directly accommodate observations such as native multispectral measurements or synthetic aperture...

Exploring the Potential of Contrastive Language-Image Pre-training for Multi-Source Remote Sensing Data

Contrastive language-image learning (CLIP) has become a key paradigm for remote sensing vision-language understanding. However, existing remote sensing contrastive learning methods are mostly built on RGB-oriented CLIP architectures, making it difficult to exploit heterogeneous sensors such as SAR, multi-spectral imagi...
