Performance characterization of integral imaging systems based on human vision

Abstract

The perceptual contrast threshold (PCT) surface is proposed for characterizing the systematic performance of integral imaging (InI) systems. The method to determine the PCT surface of InI systems is presented first. The theoretical model of the PCT surface is then derived by considering the integral contribution of an InI system as well as the human visual system. Preliminary simulated results show that the PCT can correctly describe the InI properties related to the lateral resolution, contrast, depth distance, and their trade-off relationships, which can be used to compare the systematic performance of InI systems with different design parameters. To the best of our knowledge, this is the first study of the relationship of the resolvable InI contrast with the lateral resolution and the object depth.
