Abstract: In this correspondence, the problem of designing color scanning filters for multi-illuminant color recording is considered. The filter transmittances are determined from a minimum-mean-squared orthogonal tristimulus error criterion, that minimizes the color error in estimates obtained from noisy recorded data. Nonnegativity constraints essential for physical realizability are imposed on the filter transmittances. In order to demonstrate the significant improvements obtained, the resulting... (Update)

.... however, between four and seven optimally designed spectral channels provide sufficient accuracy for common viewing illuminants [86] [88]. Note that in recording color images digitally, both the spectrum and the spatial dimensions need to be sampled. The different quality...
...noise, a single figure of merit combining the filters and the information of noise statistics is more desirable. Vrhel and Trussell [9], 10] accounted for sensor noise in the design of color scanning filters. However, the work was based on a mean squared error metric in...
