The invention discloses a multi-
modal denoising method for a hyperspectral image, which is characterized by comprising the following steps of: S1, respectively performing low-rank
tensor representation on the hyperspectral image and a registered
multispectral image by utilizing
Tucker decomposition, and extracting core tensors of the hyperspectral image and the registered
multispectral image; s2, establishing a correlation model between the hyperspectral core
tensor and the multispectral core
tensor through model-driven linear mapping or data-driven multi-layer
perceptron network; s3, iteratively solving a core tensor, a
factor matrix and correlation
model parameters by adopting an alternating direction
multiplier method; and S4, reconstructing a denoised hyperspectral image by using the optimized hyperspectral core tensor and
factor matrix. Compared with the prior art, the method has the advantages that the spectral details of the hyperspectral image and the high-
signal-to-
noise-ratio spatial information of the
multispectral image are fully mined and utilized, the restoration precision in the
mixed noise scene is effectively improved through the double-
Tucker decomposition framework and the core tensor
association strategy, and the high-quality hyperspectral image is obtained.
