Research Experience
Remote Sensing Vision-Language Models
InstructSAM: A Training-Free Framework for Instruction-Oriented Remote Sensing Object Recognition [arXiv] [Project]Yijie Zheng, Weijie Wu, Qingyun Li, Xuehui Wang, Xu Zhou, Aiai Ren, Jun Shen, Long Zhao, Guoqing Li, Xue Yang. Under review.
- Proposed InstructSAM, a novel training-free framework that enables object counting, detection, and segmentation in remote sensing imagery through user-defined instructions.
- Demonstrated SOTA performance in open-vocabulary, open-ended, and open-subclass settings.
- Reduced inference time from linear to near-constant.
