Test-Time Adaptation for Height Completion via Self-Supervised ViT Features and Monocular Foundation Models
Osher Rafaeli, Tal Svoray, Ariel Nahlieli
Accurate digital surface models (DSMs) are essential for many geospatial applications, including urban monitoring, environmental analyses, infrastructure management, and change det…
On the Effectiveness of Textual Prompting with Lightweight Fine-Tuning for SAM3 Remote Sensing Segmentation
Roni Blushtein-Livnon, Osher Rafaeli, David Ioffe +3
Remote sensing (RS) image segmentation is constrained by the limited availability of annotated data and a gap between overhead imagery and natural images used to train foundational…
Seamless High-Resolution Terrain Reconstruction: A Prior-Based Vision Transformer Approach
Osher Rafaeli, Tal Svoray, Ariel Nahlieli
High-resolution elevation data is essential for hydrological modeling, hazard assessment, and environmental monitoring; however, globally consistent, fine-scale Digital Elevation M…
SinkSAM-Net: Knowledge-Driven Self-Supervised Sinkhole Segmentation Using Topographic Priors and Segment Anything Model
Osher Rafaeli, Tal Svoray, Ariel Nahlieli
Soil sinkholes significantly influence soil degradation, infrastructure vulnerability, and landscape evolution. However, their irregular shapes, combined with interference from sha…
