The recent developments in the field of remote sensing and cloud image processing have been significantly influenced by the integration of advanced machine learning techniques, particularly deep learning and transfer learning, to address longstanding challenges such as cloud removal, cloud detection, and scene classification under cloudy conditions. A notable trend is the shift towards leveraging multi-modality data fusion, combining optical and Synthetic Aperture Radar (SAR) data, to enhance the robustness and accuracy of remote sensing applications. This approach not only mitigates the limitations posed by cloud cover but also capitalizes on the complementary strengths of different data types. Furthermore, the adoption of innovative architectures like Transformers and Generative Adversarial Networks (GANs) for specific tasks such as cloud detection and removal underscores the field's move towards more sophisticated, data-driven solutions. These advancements are characterized by their emphasis on improving interpretability, reducing computational requirements, and facilitating cross-instrument generalization, thereby broadening the applicability and efficiency of remote sensing technologies.
