@conference {LuFVS:09, title = {Designing color filter arrays for the joint capture of visible and near-infrared images}, booktitle = {Proc. IEEE International Conference on Image Processing}, year = {2009}, address = {Cairo, Egypt}, abstract = {Digital camera sensors are inherently sensitive to the near- infrared (NIR) part of the light spectrum. In this paper, we propose a general design for color filter arrays that allow the joint capture of visible/NIR images using a single sensor. We pose the CFA design as a novel spatial domain optimization problem, and provide an efficient iterative procedure that finds (locally) optimal solutions. Numerical experiments confirm the effectiveness of the proposed CFA design, which can simultane- ously capture high quality visible and NIR image pairs. }, author = {Lu, Y.M. and C. Fredembach and M.
