N2 - Spatially variant resolution method has been widely explored for Gaze Contingent Displays (GCDs). Recently several studies suggested that spatial chromatic foveation can further improve the sampling efficiency and save computational resources and communication bandwidths in GCDs. In this paper, we explore the spatial variance of the contrast sensitivity function (CSF) of the human visual system (HVS) to examine the potential of spatialchromatic foveation in GCDs. The proposed algorithm reveals that, not only the spatial resolution, but also the chrominance complexity can be monotonically degraded from the center of the field of view (FOV) to the periphery of a GCD. A perceptually-based spatialchromatic foveation metric is derived. Applying the proposed hue-resolution foveation metric, we demonstrate that over 65% of bandwidth can be saved.
