Metamer Set Based Measures of Goodness for Colour Cameras

In evaluating a set of camera sensitivities, we are mainly interested in their ability to result in colour stimuli which appears identical to the captured scene when viewed by a human eye (or a second camera). In this paper we present a measure to evaluate the likelihood that a given camera would perceive a given surface in an identical manner to a human eye. Using the metamer sets model, we show that the new measure enables us to precisely locate the regions in the reflectance space where the camera's performance is best. The new measure is advantageous to previous measures as it is independent of a specific colour space.
