Query: Gaze-Contingent Retinal Speckle Suppression for Perceptually-Matched
  Foveated Holographic Displays   Computer-generated holographic (CGH) displays show great potential and are
emerging as the next-generation displays for augmented and virtual reality, and
automotive heads-up displays. One of the critical problems harming the wide
adoption of such displays is the presence of speckle noise inherent to
holography, that compromises its quality by introducing perceptible artifacts.
Although speckle noise suppression has been an active research area, the
previous works have not considered the perceptual characteristics of the Human
Visual System (HVS), which receives the final displayed imagery. However, it is
well studied that the sensitivity of the HVS is not uniform across the visual
field, which has led to gaze-contingent rendering schemes for maximizing the
perceptual quality in various computer-generated imagery. Inspired by this, we
present the first method that reduces the "perceived speckle noise" by
integrating foveal and peripheral vision characteristics of the HVS, along with
the retinal point spread function, into the phase hologram computation.
Specifically, we introduce the anatomical and statistical retinal receptor
distribution into our computational hologram optimization, which places a
higher priority on reducing the perceived foveal speckle noise while being
adaptable to any individual's optical aberration on the retina. Our method
demonstrates superior perceptual quality on our emulated holographic display.
Our evaluations with objective measurements and subjective studies demonstrate
a significant reduction of the human perceived noise.
