|a Coded aperture snapshot spectral imaging (CASSI) is an important technique for capturing three-dimensional (3D) hyperspectral images (HSIs), and involves an inverse problem of reconstructing the 3D HSI from its corresponding coded 2D measurements. Existing model-based and learning-based methods either could not explore the implicit feature of different HSIs or require a large amount of paired data for training, resulting in low reconstruction accuracy or poor generalization performance as well as interpretability. To remedy these deficiencies, this paper proposes a novel HSI reconstruction method, which exploits the global spectral correlation from the HSI itself through a formulation of model-driven low-rank subspace representation and learns the deep prior by a data-driven self-supervised deep learning scheme. Specifically, we firstly develop a model-driven low-rank subspace representation to decompose the HSI as the product of an orthogonal basis and a spatial representation coefficient, then propose a data-driven deep guided spatial-attention network (called DGSAN) to adaptively reconstruct the implicit spatial feature of HSI by learning the deep coefficient prior (DCP), and finally embed these implicit priors into an iterative optimization framework through a self-supervised training way without requiring any training data. Thus, the proposed method shall enhance the reconstruction accuracy, generalization ability, and interpretability. Extensive experiments on several datasets and imaging systems validate the superiority of our method.
