Tiny-Dataset Scale-Consistent Diffusion Framework for Single SAR Image Building Height Estimation (opens in new tab)

Recent learning-based methods for building height estimation from a single SAR image have shown promising performance. However, existing methods are constrained by limited model learning capacity and their dependence on large-scale SAR-LiDAR paired datasets. To address these issues, this article proposes a tiny-dataset scale-consistent diffusion framework, which comprises the following three components: 1) a stable diffusion-based model is fine-tuned using just one GaoFen-3 (GF-3) SAR image t...
