Exploring Text-Guided Single Image Editing for Remote Sensing Images

Artificial intelligence generative content has significantly impacted image generation in the field of remote sensing. However, the equally important area of remote sensing image (RSI) editing has not received sufficient attention. Deep learning-based editing methods generally involve two sequential stages: generation and editing. For natural images, these stages primarily rely on generative backbones pretrained on large-scale benchmark datasets and text guidance facilitated by vision–language models (VLMs). However, it become less viable for RSIs: First, existing generative RSI benchmark datasets do not fully capture the diversity of RSIs, and is often inadequate for universal editing tasks. Second, the single text semantic corresponds to multiple image semantics, leading to the introduction of incorrect semantics. To solve above-mentioned problems, this article proposes a text-guided RSI editing method and can be trained using only a single image. A multiscale training approach is adopted to preserve consistency without the need for training on extensive benchmarks, while leveraging RSI pretrained VLMs and prompt ensembling to ensure accuracy and controllability. Experimental results on multiple RSI editing tasks show that the proposed method offers significant advantages in both CLIP scores and subjective evaluations compared to existing methods. In addition, we explore the ability of the edited RSIs to support disaster assessment tasks in order to validate their practicality.
