Measure of Goodness for Spectral Sensitivity Functions of Color Imaging Devices
نویسنده
چکیده
The ability to restore perceived colors for the output of color imaging devices is of great interest. The quality of color reproduction depends on the accuracy of the color correction function used, on the recording and rendering illumination as well as on the spectral sensitivies of the color imaging device used. Much work has been done to develop and evaluate the quality of different color correction functions under different illuminations. In this paper we present a new figure of merit (FOM) for the color reproduction ability of color imaging devices. This FOM overcomes the limitations of previously presented FOM in that its error measure is defined in the percetually uniform CIELab color space, it takes account for recording noise and it is independent on the color correction function used. We can calculate a measure of uncertainty with respect to the perceived colors that might have led to this sensors response.

متن کاملNew Figure of Merit for Color Reproduction Ability of Color Imaging Devices using the Metameric Boundary Descriptor
A measure for the color reproduction ability of a color imaging device is important for comparison purposes as well as for the sensor design process. Several figures of merit which describe this ability in a single measure have been proposed in the past. All these measures have shortcomings in that their error measure is defined in a non-representative color space for human color perception, or...

متن کاملOptimum spectral sensitivity functions for single sensor color imaging
A cost-effective and convenient approach for color imaging is to use a single sensor and mount a color filter array (CFA) in front of it, such that at each spatial position the scene information in only one color channel is captured. To estimate the missing colors at each pixel, a demosaicing algorithm is applied to the CFA samples. Besides the filter arrangement and the demosaicing method, the...

The skin color signal is the product of skin reflectances and spectral power distribution of illuminants. In this paper we use principal component analysis to obtain basis functions for an ensemble of skin color signals and test the reconstruction goodness with different number of basis functions and types of normalization. We demonstrate the usefulness of the basis functions in two application...
