📌 Master’s Thesis – Foundation Models for Remote Sensing (Hyperspectral Focus)

🌍 Overview

Foundation models have triggered a paradigm shift in computer vision, achieving strong generalization capabilities with little or no finetuning. These advances are largely driven by self-supervised learning algorithms, which enable the learning of useful representations on unlabeled data. These methods are now being applied to domain-specific problems in medical imaging, genomics, and remote sensing.

Remote sensing faces unique challenges, such as the diversity of sensors with varying spatial, spectral, and temporal characteristics. Common types of sensors include multispectral and hyperspectral sensors, synthetic aperture radar (SAR), and LiDAR, each providing distinct features.

Several efforts have focused on training foundation models for single sensor imagery and multi-sensor data. However, more efforts are needed to integrate more sensors and train truly general-purpose foundation models. For instance, the hyperspectral modality is often neglected due to the high cost of data acquisition, and large-scale pre-training of hyperspectral foundation models is still under-explored. Furthermore, the community lacks a systematic approach to evaluate these models, and the development of consistent and fair benchmarking practices is needed.
