It is possible to achieve improved color accuracy with a color camera by placing a color filter in front of the camera. Unfortunately, the color filter will block some of the light entering the camera, which will result in additional noise in the recorded data. This paper provides an initial investigation into finding an optimal solution to the filter design, in the presence of noise.
