Diffusion Models Meet Remote Sensing: Principles, Methods, and Perspectives
It addresses the need for a systematic overview to help remote sensing researchers leverage diffusion models effectively, but it is incremental as it focuses on reviewing and summarizing existing applications rather than introducing new methods.
This paper provides a comprehensive review of how diffusion models, a state-of-the-art deep generative approach, are applied to remote sensing tasks such as image generation, enhancement, and interpretation, synthesizing existing research to highlight their potential and guide future work.
As a newly emerging advance in deep generative models, diffusion models have achieved state-of-the-art results in many fields, including computer vision, natural language processing, and molecule design. The remote sensing (RS) community has also noticed the powerful ability of diffusion models and quickly applied them to a variety of tasks for image processing. Given the rapid increase in research on diffusion models in the field of RS, it is necessary to conduct a comprehensive review of existing diffusion model-based RS papers, to help researchers recognize the potential of diffusion models and provide some directions for further exploration. Specifically, this article first introduces the theoretical background of diffusion models, and then systematically reviews the applications of diffusion models in RS, including image generation, enhancement, and interpretation. Finally, the limitations of existing RS diffusion models and worthy research directions for further exploration are discussed and summarized.
