Publication number: 20220414823Abstract: Peripheral-vision expanded images are streamed to a video streaming client. The peripheral-vision expanded images are generated from source images in reference to view directions of the viewer at respective time points. View direction data is collected and received in real time while the viewer is viewing display images derived from the peripheral-vision expanded images. A second peripheral-vision expanded image is generated from a second source image in reference to a second view direction of the viewer at a second time point. The second peripheral-vision expanded image has a focal-vision image portion covering the second view direction of the viewer and a peripheral-vision image portion outside the focal-vision image portion. The second peripheral-vision expanded image is transmitted to the video streaming client.Type: ApplicationFiled: August 31, 2022Publication date: December 29, 2022Inventors: Alexandre CHAPIRO, Chaitanya ATLURU, Chun Chi WAN, Haricharan LAKSHMAN, William ROZZI, Shane RUGGIERI, Ajit NINAN

Patent number: 11393113Abstract: Bordering pixels delineating a texture hole region in an image are identified. Depth values of the bordering pixels are recorded. The depth values are automatically clustered into two depth value clusters with a depth value threshold separating the two depth value clusters. A subset of bordering background pixels is identified in the bordering pixels as those with depth values in one of the two depth value clusters that is declared as a background depth value cluster. The subset of bordering background pixels is used to predict texture hole pixel values in the texture hole region based on multiple candidate prediction directions. Quality indicator values are computed for the multiple candidate prediction directions and used to select a specific candidate prediction direction for filling in final texture hole pixel values in the texture hole region of the image.Type: GrantFiled: February 25, 2020Date of Patent: July 19, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Wenhui Jia, Haricharan Lakshman, Ajit Ninan

Publication number: 20210373340Abstract: A wearable device includes circuitry on substrate. The substrate is coupled to an optical element in an optical stack. A refractive index of the substrate perceptually matches a refractive index of the optical component. The circuitry is imperceptible to the viewer wearing the device, despite that the circuitry has a view of (or, as an example, an unobstructed line of sight to) the viewer's eye. The circuitry can include a camera or an emitter, or both. The camera captures one or more reflections of the emitter from the viewer's eye. In a specific embodiment, the substrate includes a waveguide, Fresnel lenses, or lens to bend light rays around from the circuitry to achieve the imperceptibility. In alternative embodiment, the circuitry can be a piezoelectric device, liquid crystal controller, or any electronic circuitry relevant for a wearable device.Type: ApplicationFiled: September 20, 2019Publication date: December 2, 2021Applicant: Dolby Laboratories Licensing CorporationInventors: Titus Marc DeVine, Chun Chi Wan, Chaitanya Atluru, Ajit NINAN
