N-LMMSE Demosaicing for Spectral Filter Arrays
  DOI :  10.2352/J.ImagingSci.Technol.2017.61.4.040407  Published OnlineJuly 2017

Spectral filter array (SFA) technology requires development on demosaicing. The authors extend the linear minimum mean square error with neighborhood method to the spectral dimension. They demonstrate that the method is fast and general on Raw SFA images that span the visible and near infra-red part of the electromagnetic range. The method is quantitatively evaluated in simulation first, then the authors evaluate it on real data by the use of non-reference image quality metrics applied on each band. Resulting images show a much better reconstruction of text and high frequencies at the expense of a zipping effect, compared to the benchmark binary-tree method. © 2017 Society for Imaging Science and Technology.
