Embodiment 1
[0154] 1. HSI denoising experiment based on zero mean noise
[0155] First add zero-mean Gaussian noise to the CAVE, ICVL and Washington DC Mall datasets with noise levels 30, 50, 70 and random IID Gaussian noise. The quantitative evaluation results of various denoising methods on the CAVE, ICVE, and Washington DC datasets in the case of zero-mean Gaussian noise are shown in Table 1. It is not difficult to see that the proposed 3D-DUSSD model achieves better performance than other methods on most evaluation metrics. In addition, FastHyDe and HSI-SDeCNN and QRNN3D both show excellent denoising performance, but FastHyDe does not work well for blind noise, HSI-SDeCNN is good at knowing the noise level in advance, QRNN3D uses different noise intensities samples to train the network, but its model needs to be fine-tuned for a different dataset. The method uses only non-IID Gaussian noise to simulate training samples to train a single model, and shows better performance on differe...
