Combined the Data-Driven with Model-Driven Stragegy: A Novel Framework for Mixed Noise Removal in Hyperspectral Image

In this paper, we present a novel hyperspectral image (HSI) denoising method especially for mixed noise removal. The proposed method combines both data-driven with model-driven strategy via a deep spatio-spectral variational structure. The mixed noise estimation and removal are collaboratively derived through fusing the Bayesian spatio-spectral posterior and deep learning model. The framework can both utilize the logicality of traditional model-driven methods, and the high efficiency of data-driven methods for parameters optimizing. Simulated and actual experiments demonstrate that the presented method outperforms other existing methods for HSI mixed noise removal, on both reconstructing effects and time-consuming.
