Figure 2: Workflow for the reported algorithm. The iterations up-date the set of reference spectra to be employed in the linear mix-ing model, keeping as much information as possible in a givennoisy band and discarding all noise contributions.
Figure 3: Sample steps from the iterative reference spectra selection. The reported images show the reconstruction error in a sampleband at 434 nm, after a low-pass filtering carried out in the frequency domain
Figure 5: Image in fig. 4 after denoising. Land and boats havebeen masked out.
