Publication number: 20240013508Abstract: Systems and methods are related to daltonizing images. An image decoder can receive a first image and a second image. The images can be associated with a first metadata and second metadata, respectively. The image decoder and determine a color mapping for the first image and the second image based on the first metadata and the second metadata. The image decoder can process the images in a color vision deficiency (CVD) processor and based on the images and their associated metadata generate daltonized images which are sent to a display.Type: ApplicationFiled: June 28, 2023Publication date: January 11, 2024Applicant: Avago Technologies International Sales Pte.

Publication number: 20230133015Abstract: Methods, systems, and devices for improving security of media streams are disclosed. The system can receive a decoded media stream from a media decoding pipeline that receives and decodes an encoded media stream. The system can identify, based on the decoded media stream, a set of features to generate, and generate the set of features using the decoded media stream. Such features may include luma histograms, pixel intensity data, motion vectors, edge detection, audio gain, tonal information, pitch information, among other types of features. The system can provide the set of features to a processor executing a machine-learning model, wherein the processor executing the machine-learning model is prevented from accessing the decoded media stream by the device.Type: ApplicationFiled: October 28, 2021Publication date: May 4, 2023Inventors: Wade Wan, Jason W.

Publication number: 20170118489Abstract: Compounding reproduction errors in the luminance of a pixel encoded by a non-constant luminance video encoder is High Dynamic Range (HDR) video content, which is starting to become more widely supported by commercially available display devices. HDR video content contains information that covers a wider luminance range than traditional, non-HDR video content known as Low Dynamic Range (LDR) video content. The present disclosure is directed to an apparatus and method for reducing errors in reproduced luminance of HDR video content (and other types of video content) at a video encoder and/or video decoder due to non-constant luminance video encoding.Type: ApplicationFiled: November 2, 2015Publication date: April 27, 2017Applicant: Broadcom CorporationInventors: Gheorghe BERBECEL, Richard Hayden Wyman
