GeoRoPE: Ground-Aware Rotary Adaptation for Remote Sensing Foundation Models

Yu Luo, Kun Hu, Mengwei He +7

Remote-sensing foundation models (RSFMs) benefit from pretraining on imagery from multiple sensors and ground sampling distances (GSDs), but such exposure alone does not resolve sc…

Split-Fuse-Transport: Annotation-Free Saliency via Dual Clustering and Optimal Transport Alignment

Muhammad Umer Ramzan, Ali Zia, Abdelwahed Khamis +3

Salient object detection (SOD) aims to segment visually prominent regions in images and serves as a foundational task for various computer vision applications. We posit that SOD ca…
