Spectral estimation techniques for the spectral calibration of a color image scanner

Not Accessible

Abstract

Several methods of spectral sensitivity estimation for color image scanners are developed and evaluated. The estimation procedure involves response measurements of the scanner through a set of spectrally selective filters. These measurements form the observations for generalized inverse, smoothing, and Wiener estimation processes. Wiener estimation is found to provide the best results.
