Adaptive loudness normalization for audio object clustering
12 Mar 24
A method of processing audio content including a plurality of audio elements comprises: clustering the plurality of audio elements into a plurality of clusters of audio elements; and for a cluster among the plurality of clusters: for each audio element in the cluster, determining a measure of energy that the audio element contributes to the cluster; for at least one audio element in the cluster, determining a compensation gain based at least in part on the measures of energy for the audio elements in the cluster; and applying the compensation gain to the at least one audio element in the cluster.

Method and apparatus for controlling enhancement of low-bitrate coded audio
12 Mar 24
Described herein is a method of low-bitrate coding of audio data and generating enhancement metadata for controlling audio enhancement of the low-bitrate coded audio data at a decoder side, including the steps of: (a) core encoding original audio data at a low bitrate to obtain encoded audio data; (b) generating enhancement metadata to be used for controlling a type and/or amount of audio enhancement at the decoder side after core decoding the encoded audio data; and (c) outputting the encoded audio data and the enhancement metadata.

Utility
Signal reshaping for high dynamic range signals
5 Mar 24
In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and/or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ).

Utility
HDR image generation from single-shot HDR color image sensors
5 Mar 24
A method for generating an high-dynamic-range (HDR) color image from a dual-exposure-time single-shot HDR color image sensor includes obtaining pixel values generated by a local region of sensor pixels of the image sensor, determining a motion parameter for the local region from pixel values associated with a first color, and demosaicing the pixel values of the local region to determine, for each of three colors, an output value of the images pixel, wherein relative contributions of short-exposure-time pixels and long-exposure-time pixels to the output value are weighted according to the motion parameter.
