摘要:

全色锐化技术通过融合高空间分辨率全色图像和低空间分辨率多光谱图像, 提高多光谱图像的空间分辨率. 随着深度学习的发展, 构建深度模型逐渐成为了全色锐化的主流方法. 然而, 目前的主流技术都是基于某个特定卫星的数据集进行模型训练, 训练出的模型也仅能用于该卫星数据集的全色锐化, 而对于数据集不足的卫星, 相关研究尚未充分开展. 针对这种现象, 提出了一种一体化的全色锐化方法, 通过提示学习技术, 同时针对不同卫星的数据集进行训练, 训练出的一体化模型可应用于不同卫星数据集的全色锐化. 实验表明, 该模型能够达到当前主流水平并且具有良好的泛化性.

Abstract:

Pansharpening is an image processing technique primarily used to enhance the spatial resolution of remote sensing images by fusing high spatial resolution panchromatic images with low spatial resolution multispectral images. With the development of deep learning, building deep models has gradually become the mainstream method for pansharpening. However, current mainstream technologies are based on training models using datasets from specific satellites, limiting the application of the trained models to fuse images from only those satellite datasets, without covering satellites with limited datasets. Addressing this issue, this paper proposes a unified pansharpening approach that leverages prompt learning technology to train models on datasets from different satellites. The trained unified model can be applied to fuse images from various satellite datasets. Experimental results demonstrate that the model achieves state-of-the-art performance and exhibits good generalization capabilities.

Key words: pansharpening, remote sensing images, image fusion, deep learning, prompt learning
