摘要:

全色图像的空间特征和多光谱波段的光谱信息是全色锐化的关键问题。本文提出了一种基于金字塔的深度融合框架,该框架在不同尺度上保留了光谱和空间特征。通过将相应的低分辨率多光谱图像作为网络在每个尺度上的残差分量来保留光谱信息。通过在每个尺度上用全色图像的高频与相应的低分辨率多光谱图像一起训练网络来保留空间信息。不同网络的参数在金字塔中共享,以便在不同尺度上一致地添加空间细节。这些参数也在特定规模的网络内的融合层之间共享。实验表明,所提出的架构优于最先进的泛锐化模型。所提出的模型、代码和数据集可在https://github.com/sohaibali01/deep_pyramid_fusion上公开获得。

英文摘要:

Retaining spatial characteristics of panchromatic image and spectral information of multispectral bands is a critical issue in pansharpening. This paper proposes a pyramid based deep fusion framework that preserves spectral and spatial characteristics at different scales. The spectral information is preserved by passing the corresponding low resolution multispectral image as residual component of the network at each scale. The spatial information is preserved by training the network at each scale with the high frequencies of panchromatic image alongside the corresponding low resolution multispectral image. The parameters of different networks are shared across the pyramid in order to add spatial details consistently across scales. The parameters are also shared across fusion layers within a network at a specific scale. Experiments suggest that the proposed architecture outperforms state of the art pansharpening models. The proposed model, code and dataset is publicly available at https://github.com/sohaibali01/deep_pyramid_fusion.
