AI总结:

针对纯语言指令在复杂遥感场景中传递信息低效、自然场景提示策略难适配遥感数据的问题,提出首个遥感视觉提示多模态大语言模型EarthMarker,构建RSVP数据集,实现多粒度遥感图像解译。

摘要:

提示学习的最新进展允许用户通过多轮对话与人工智能(AI)工具交互,实现对图像的交互式理解。然而,在复杂的遥感(RS)场景中,仅使用纯语言指令传递信息既困难又低效,这将严重阻碍对图像潜在内容的深度理解。此外,由于显著的领域差异,自然场景中的现有提示策略难以应用于遥感数据的解译。为应对这些挑战,本文在遥感领域提出了首个基于视觉提示的多模态大语言模型(MLLM)——EarthMarker。EarthMarker能够通过利用视觉提示(即框和点)在图像、区域和点级别解译遥感图像。具体而言,本文开发了一种共享视觉编码方法,以建立输入图像的多尺度表示与各种视觉提示之间的空间模式解译关系。随后,将混合的视觉-空间表示与语言指令关联,构建联合提示,从而实现对遥感图像复杂内容的解译。此外,为弥合自然数据与遥感数据之间的领域差距,并有效将领域级知识从自然场景迁移到遥感领域,本文开发了一种跨域学习策略来促进遥感图像理解。另外,为解决遥感视觉提示数据的缺乏问题,本文构建了一个名为RSVP的数据集,该数据集具有多模态多粒度视觉提示指令跟随功能。我们的代码和数据集可在https://github.com/wivizhang/EarthMarker获取。

英文摘要:

Recent advances in prompt learning have allowed users to interact with artificial intelligence (AI) tools in multi-turn dialogue, enabling an interactive understanding of images. However, it is difficult and inefficient to deliver information in complicated remote sensing (RS) scenarios using plain language instructions alone, which would severely hinder deep comprehension of the latent content in imagery. Besides, existing prompting strategies in natural scenes are hard to apply to interpret the RS data due to significant domain differences. To address these challenges, the first visual prompting-based multi-modal large language model (MLLM) named EarthMarker is proposed in the RS domain. EarthMarker is capable of interpreting RS imagery at the image, region, and point levels by levering visual prompts (i.e., boxes and points). Specifically, a shared visual encoding method is developed to establish the spatial pattern interpretation relationships between the multi-scale representations of input images and various visual prompts. Subsequently, the mixed visual-spatial representations are associated with language instructions to construct joint prompts, enabling the interpretation of intricate content of RS imagery. Furthermore, to bridge the domain gap between natural and RS data, and effectively transfer domain-level knowledge from natural scenes to the RS domain, a cross-domain learning strategy is developed to facilitate the RS imagery understanding. In addition, to tackle the lack of RS visual prompting data, a dataset named RSVP featuring multi-modal multi-granularity visual prompts instruction-following is constructed. Our code and dataset are available at https://github.com/wivizhang/EarthMarker.
