Patent number: 10713838Abstract: The present invention facilitates efficient and effective image processing. A network can comprise: a first system configured to perform a first portion of lighting calculations for an image and combing results of the first portion of lighting calculations for the image with results of a second portion of lighting calculations; and a second system configured to perform the second portion of lighting calculations and forward the results of the second portion of the lighting calculations to the first system. The first and second portion of lighting calculations can be associated with indirect lighting calculations and direct lighting calculations respectively. The first system can be a client in a local location and the second system can be a server in a remote location (e.g., a cloud computing environment). The first system and second system can be in a cloud and a video is transmitted to a local system.Type: GrantFiled: May 5, 2014Date of Patent: July 14, 2020Assignee: NVIDIA CorporationInventors: Morgan McGuire, David Luebke, Cyril Crassin, Peter-Pike Sloan, Peter Shirley, Brent Oster, Christopher Wyman, Michael Mara

Patent number: 10699383Abstract: Methods are disclosed herein to blur an image to be displayed on a stereo display (such as virtual or augmented reality displays) based on the focus and convergence of the user. The methods approximate the complex effect of chromatic aberration on focus, utilizing three (R/G/B) simple Gaussian blurs. For transparency the methods utilize buffers for levels of blur rather than depth. The methods enable real-time chromatic-based blurring effects for VR/AR displays.Type: GrantFiled: December 10, 2018Date of Patent: June 30, 2020Assignee: NVIDIA Corp.Inventors: Morgan McGuire, Kaan Aksit, Pete Shirley, David Luebke

Patent number: 10642311Abstract: A method for displaying a near-eye light field display (NELD) image is disclosed. The method comprises determining a pre-filtered image to be displayed, wherein the pre-filtered image corresponds to a target image. It further comprises displaying the pre-filtered image on a display. Subsequently, it comprises producing a near-eye light field after the pre-filtered image travels through a microlens array adjacent to the display, wherein the near-eye light field is operable to simulate a light field corresponding to the target image. Finally, it comprises altering the near-eye light field using at least one converging lens, wherein the altering allows a user to focus on the target image at an increased depth of field at an increased distance from an eye of the user and wherein the altering increases spatial resolution of said target image.Type: GrantFiled: November 13, 2018Date of Patent: May 5, 2020Assignee: NVIDIA CORPORATIONInventors: Douglas Lanman, David Luebke

Patent number: 9934714Abstract: System and method of displaying images in temporal superresolution by multiplicative superposition of cascaded display layers integrated in a display device. Using an original video with a target temporal resolution as a priori, a factorization process is performed to derive respective image data for presentation on each display layer. The multiple layers are refreshed in staggered intervals to synthesize a video with an effective refresh rate exceeding that of each individual display layer, e.g., by a factor equal to the number of layers. Further optically averaging neighboring pixels can minimize artifacts.Type: GrantFiled: March 17, 2015Date of Patent: April 3, 2018Assignee: NVIDIA CORPORATIONInventors: Felix Heide, Douglas Lanman, Dikpal Reddy, Jan Kautz, Kari Pulli, David Luebke

Patent number: 9892669Abstract: System and method of displaying images in spatial/temporal superresolution by multiplicative superposition of cascaded display layers integrated in a display device. Using an original image with a target spatial/temporal resolution as a priori, a factorization process is performed to derive respective image data for presentation on each display layer. The cascaded display layers may be progressive and laterally shifted with each other, resulting in an effective spatial resolution exceeding the native display resolutions of the display layers. Factorized images may be refreshed on respective display layers in synchronization or out of synchronization.Type: GrantFiled: March 17, 2015Date of Patent: February 13, 2018Assignee: Nvidia CorporationInventors: Felix Heide, Douglas Lanman, Dikpal Reddy, Jan Kautz, Kari Pulli, David Luebke

Patent number: 9643123Abstract: Methods and compositions useful, for example, for physical solvent carbon capture. A method comprising: contacting at least one first composition comprising carbon dioxide with at least one second composition to at least partially dissolve the carbon dioxide of the first composition in the second composition, wherein the second composition comprises at least one siloxane compound which is covalently modified with at least one non-siloxane group comprising at least one heteroatom. Polydimethylsiloxane (PDMS) materials and ethylene-glycol based materials have high carbon dioxide solubility but suffer from various problems. PDMS is hydrophobic but suffers from low selectivity. Ethylene-glycol based systems have good solubility and selectivity, but suffer from high affinity to water. Solvents were developed which keep the desired combinations of properties, and result in a simplified, overall process for carbon dioxide removal from a mixed gas stream.Type: GrantFiled: October 27, 2014Date of Patent: May 9, 2017Assignees: CARNEGIE MELLON UNIVERSITY, U.S. DEPARTMENT OF ENERGYInventors: Hunaid Nulwala, David Luebke

Patent number: 9576340Abstract: A technique for efficiently compressing rendered three-dimensional images in a remote rendering system adds a novel render-assisted prediction function to an existing video compression framework, such as the standard H.264/5 framework. Auxiliary rendering information is separated from rendering information used to describe a reference image by a server system. A client system may alter the auxiliary data and generate a new image based on the reference image and rendered scene information from the auxiliary data without creating additional network bandwidth or server workload.Type: GrantFiled: December 26, 2012Date of Patent: February 21, 2017Assignee: NVIDIA CorporationInventors: Dawid Stanislaw Pajak, David Luebke, Scott Saulters
