The multispectral remote sensing image (MS-RSI) is blurred existing multispectral camera due to various hardware limitations. In this paper, we propose a novel structural compact core tensor dictionary learning (SCCTDL) model for MS-RSI deblurring. First, the multispectral patch is modeled by three-order tensor and high-order singular value decomposition is applied to the tensor. Then the task of MS-RSI deblurring is formulated as a minimum sparse core tensor estimation problem. To improve the accuracy of core tensor coding, the core tensor estimation based on the structural compact principle is introduced into the SCCTDL model to exploit abundant structural similarity in image. Experimental results suggest that our method outperforms several existing MS-RSI deblurring methods in both subjective image quality and visual perception.
