Abstract

Several experiments are performed to investigate the relation between the information theoretic measures and the visual target distinctness measured by human observers (Sec. 4.5). First, a psychophysical experiment is performed in which human observers estimate the visual distinctness of targets in a database. The subjective ranking induced by the psychophysical target distinctness is estimated by the measure of information between the original scene and an image of the same scene in which the target support has been artificially filled in with the local background. A relationship is then established between the computational and the psychophysical target distinctness estimate. The main conclusions of the chapter are summarized in Sec. 4.6.
