Abstract: A method may include generating a hybrid image associated with a first interpretation corresponding to a first value of a media parameter and a second interpretation corresponding to a second value of the media parameter. The hybrid image may include a first visibility ratio between the first interpretation and the second interpretation. The method may include refining the hybrid image to create a refined hybrid image that includes a second visibility ratio different than the first visibility ratio. The method may include displaying the refined hybrid image, and receiving a user input related to a first perception of the refined hybrid image by a user. The method may include determining, based at least in part on the user input, an optimized value of the media parameter, and providing output media for display to the user to a playback device according to the optimized value of the media parameter.

Abstract: Guided filtering is applied, with a camera raw image as a guidance image, to a first image to generate an intermediate image. A dynamic range mapping is performed on the intermediate image to generate a second image of a different dynamic range. The second image is used to generate specific local reshaping function index values for selecting specific local reshaping functions. The specific local reshaping functions are applied to the second image to generate a locally reshaped image.

Abstract: Image data is received for rendering an image on an image display to a viewer (402). The image data specifies a pixel value of the image for a pixel of the image display to render. The pixel value for the pixel includes multiple component pixel values corresponding to multiple color components of a color space. A color gamut locational value of the pixel value is computed based on two or more component pixel values in the multiple component pixel values of the pixel value specified for the pixel (404). The color gamut locational value is used to determine whether bandwidth broadening is to be applied to image rendering light produced by the pixel of the image display to render the pixel value (406). The image rendering light is directed to the viewer.

Abstract: Audio perception in local proximity to visual cues is provided. A device includes a video display, first row of audio transducers, and second row of audio transducers. The first and second rows can be vertically disposed above and below the video display. An audio transducer of the first row and an audio transducer of the second row form a column to produce, in concert, an audible signal. The perceived emanation of the audible signal is from a plane of the video display (e.g., a location of a visual cue) by weighing outputs of the audio transducers of the column. In certain embodiments, the audio transducers are spaced farther apart at a periphery for increased fidelity in a center portion of the plane and less fidelity at the periphery.

The content-creation-user-specific modified prediction models are used to predict operational parameter values of content-creation-user-specific backward reshaping mappings for backward reshaping SDR images into mapped HDR images of at least one content-creation-user-adjusted HDR appearance.

Abstract: Methods and systems for the super resolution of high dynamic range (HDR) video are described. Given a sequence of video frames, a current frame and two or more neighboring frames are processed by a neural-network (NN) feature extraction module, followed by a NN upscaling module, and a NN reconstruction module. In parallel, the current frame is upscaled using traditional up-sampling to generate an intermediate up-sampled frame. The output of the reconstruction module is added to the intermediate up-sampled frame to generate an output frame. Additional traditional up-sampling may be performed on the output frame to match the desired up-scaling factor, beyond the up-scaling factor for which the neural network was trained.

It is determined that the view direction of the second user is towards a third user at a first time point in the communication session. The view direction of the second user is used to modify a pre-adapted visual depiction of the second user into an adapted visual depiction of the second user. The adapted visual depiction of the second user is rendered, to the first user, on an image display operating with the communication client device.

Abstract: Encoding/decoding an audio signal having one or more audio components, wherein each audio component is associated with a spatial location. A first audio signal presentation (z) of the audio components, a first set of transform parameters (w(f)), and signal level data (?2) are encoded and transmitted to the decoder. The decoder uses the first set of transform parameters (w(f)) to form a reconstructed simulation input signal intended for an acoustic environment simulation, and applies a signal level modification (?) to the reconstructed simulation input signal. The signal level modification is based on the signal level data (?2) and data (p2) related to the acoustic environment simulation. The attenuated reconstructed simulation input signal is then processed in an acoustic environment simulator. With this process, the decoder does not need to determine the signal level of the simulation input signal, thereby reducing processing load.
