Publication number: 20230345055Abstract: 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). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.Type: ApplicationFiled: June 27, 2023Publication date: October 26, 2023Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Robin Atkins, Peng Yin, Taoran Lu, Jaclyn Anne Pytlarz

Patent number: 11776099Abstract: Methods and systems for generating an image quality metric are described. A reference and a test image are first converted to the ITP color space. After calculating difference images ?I, ?T, and ?P, using the color channels of the two images, the difference images are convolved with low pass filters, one for the I channel and one for the chroma channels (I or P). The image quality metric is computed as a function of the sum of squares of filtered ?I, ?T, and ?P values. The chroma low-pass filter is designed to maximize matching the image quality metric with subjective results.Type: GrantFiled: June 10, 2021Date of Patent: October 3, 2023Assignee: Dolby Laboratories Licensing CorporationInventors: Robert Wanat, Robin Atkins, Anustup Kumar Atanu Choudhury, Scott Daly, Jaclyn Anne Pytlarz

Publication number: 20230217067Abstract: The described embodiments include systems and methods for producing and adapting images, such as video images, for presentation on display devices that have various different aspects ratios, such as 4:3, 16:9, 9:16, etc. In one embodiment, a method for producing content, such as video images, can begin by selecting an original aspect ratio and determining, within at least a first scene in the content, a position of a subject in the first scene. In one embodiment, the original aspect ratio can be substantially square (e.g., 1:1). Metadata can then be created, based on the position of the subject in the first scene, to guide playback devices to asymmetrically crop the content, relative to the position, for display on display devices that have aspect ratios that are different than the original aspect ratio. Other methods and systems are also described.Type: ApplicationFiled: June 9, 2021Publication date: July 6, 2023Applicant: Dolby Laboratories Licensing CorporationInventors: Robin ATKINS, Suzanne FARRELL, Per Jonas Andreas KLITTMARK
