    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for gamma lookup table compression based on dimensionality reduction. In one aspect, a method includes obtaining a selection of a particular display condition for a display panel from among different display conditions for the display panel, selecting, based on the selection of the particular display condition, a set of weights for a set of basis functions from among different sets of weights that correspond to the different display conditions for the display panel, determining a gamma lookup table for the particular display condition for the display panel based on the set of weights that were selected and the set of basis functions, and remapping an image to be output on the display panel based on the gamma lookup table for the particular display condition.

    Abstract: A method and device for reducing power consumption of display devices proposes to reduce the total amount of light emitted in a perceptually indistinguishable manner based on the on the human visual sensitivity at the position of a pixel. The visibility of the processing can be made to remain provably below threshold, whereas other techniques may not be able to provide such proof. This is achieved by determining a minimum detectable modulation or a corresponding just-noticeable difference based on frequency intensity information for a pixel representative of how much there is of a set of frequencies at the pixel and a contrast sensitivity function representative of a model of human vision that predicts which contrasts at which frequencies are visible to the human eye. Pixel values may be reduced based on this minimum detectable modulation or just-noticeable difference. The contrast sensitivity function may be given by Barten's model and the frequency intensity information may be based on a hierarchical map built using a discrete wavelet transform or a continuous wavelet transform.

    Abstract: A multi-view (MV) transportation hub information system is provided, which includes: a MV display including one or more multi-view (MV) pixels, wherein each MV pixel is configured to emit beamlets in different directions; a sensing system configured to detect a first location of a first blob and a second location of a second blob; an input node configured to receive a first attribute of a first viewer and a second attribute of a second viewer; and a system controller configured to perform user tagging to tag the first blob with the first attribute and to tag the second blob with the second attribute. The system controller controls the MV pixels to project a first image based on the first attribute to the first viewer tagged with the first blob, and to project a second image based on the second attribute to the second viewer tagged with the second blob.
