Zero-Shot AI for Remote Sensing: A New Pipeline for Automated Image Segmentation

Chinese Academy of Sciences — Wed, 26 Feb 2025 08:20:02 EST

Researchers have developed a pipeline that integrates zero-shot AI detection and segmentation tools to achieve robust, automated segmentation of remote sensing images. By leveraging a sliding window hyper-inference approach and an outlier rejection step, the pipeline enhances the identification of features such as buildings, trees, and vehicles in aerial and satellite imagery. This solution is implemented as a user-friendly Python package, LangRS, making advanced remote sensing segmentation accessible to a wide range of users.

The Galactic Journey of our Solar System

University of Vienna — Tue, 25 Feb 2025 05:00:28 EST

An international research team led by the University of Vienna has discovered that the Solar System traversed the Orion star-forming complex, a component of the Radcliffe Wave galactic structure, approximately 14 million years ago. This journey through a dense region of space could have compressed the heliosphere, the protective bubble surrounding our solar system, and increased the influx of interstellar dust, potentially influencing Earth's climate and leaving traces in geological records. The findings, published in Astronomy & Astrophysics, offer a fascinating interdisciplinary link between astrophysics, paleoclimatology, and geology.
