Embodiment Construction
[0040] Such as figure 1 As shown, the implementation steps of the hyperspectral image denoising method based on adaptive rank correction in this embodiment include:
[0041] 1) For degraded hyperspectral images After matrixing, the inexact augmented Lagrangian multiplier algorithm (IALM) is used for initial estimation, and the clean hyperspectral image of the initial estimation is obtained
[0042] 2) For degraded hyperspectral images Initial estimated clean hyperspectral image Blocking and matrixing are performed respectively to obtain matrixed block degraded hyperspectral image Y and matrix block initially estimated clean hyperspectral image X;
[0043] 3) Establish a hyperspectral image denoising model based on adaptive rank correction for each matrixed block degraded hyperspectral image Y, matrix block initially estimated clean hyperspectral image X, and hyperspectral image denoising model based on adaptive rank correction The noise model uses an adaptive rank cor...
