Abstract:
A method for correcting for hue shifts includes parameterizing the conversion of long-medium-short (LMS) spectral sensitivities of the human eye to a human observer function, and applying a non-linear transformation between the LMS and human observer function in order to correct for the hue shifts. A system for correcting for hue shifts is also provided. The system includes a controller for parameterizing the conversion of LMS spectral sensitivities of the human eye to a human observer function and applying a non-linear transformation between the LMS and human observer function in order to correct for the hue shifts in the image. The system can also include an output device for presenting the hue corrected image.
