Figures of Merit for Color Scanners - Sharma, Trussell (1997) (3 citations) Self-citation (Sharma Trussell) (Correct)
....the scanner camera sensors are noiseless. In the real world, sensor noise is inevitable. Since filter sets need not be equally robust in the presence of measurement 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 the perceptually nonuniform CIE XYZ space. In this paper, a new figure of merit for color scanners cameras is considered that can be viewed as extension of the ....
....span instead) Since the choice of particular CIE XYZ color matching functions to represent the human visual space was made for mathematical convenience and not for any reasons of perceptual uniformity [1] 2] this independence is a desirable feature. It may also be noted that Vrhel and Trussell [9], 10] formulated the problem of designing color scanning filters in terms of the maximization of the numerator in (16) and thus implicitly used the above FOM. If measurement noise is ignored, i.e. it is assumed that , the figure of merit in (16) reduces to the datadependent measure of goodness ....

....of the Luther Ives condition would SHARMA et al. COLOR IMAGING FOR MULTIMEDIA 1099 require 3 channels for different viewing illuminants. In practice, 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 measures mentioned above consider only the spectral sampling aspect of the above problem. These are therefore suitable for evaluating the color recording ....
