Patent number: 12008710Abstract: This disclosure relates to methods, non-transitory computer readable media, and systems that can render a virtual object in a digital image by using a source-specific-lighting-estimation-neural network to generate three-dimensional (“3D”) lighting parameters specific to a light source illuminating the digital image. To generate such source-specific-lighting parameters, for instance, the disclosed systems utilize a compact source-specific-lighting-estimation-neural network comprising both common network layers and network layers specific to different lighting parameters. In some embodiments, the disclosed systems further train such a source-specific-lighting-estimation-neural network to accurately estimate spatially varying lighting in a digital image based on comparisons of predicted environment maps from a differentiable-projection layer with ground-truth-environment maps.Type: GrantFiled: December 6, 2022Date of Patent: June 11, 2024Assignees: Adobe Inc., Universite LavalInventors: Kalyan Sunkavalli, Yannick Hold-Geoffroy, Christian Gagne, Marc-Andre Gardner, Jean-Francois Lalonde

Patent number: 9782379Abstract: The present invention provides a method for the stimulation of secretion or expression of muscular IL-6 in a subject with the administration of Protectin DX (PDX). Particularly, the increase in circulating levels of IL-6 originating from the subject muscles is useful for regulating blood glucose and suppressing lipid-induced inflammation and other related inflammatory conditions such as insulin resistance, metabolic syndrome, type-2 diabetes, hypertension and cardiovascular diseases. Alternatively, the increase in muscular IL-6 expression in a subject may also be useful for increasing energy supply during exercise, or facilitating muscular recovery after strenuous effort.Type: GrantFiled: January 23, 2014Date of Patent: October 10, 2017Assignee: Universite LavalInventors: Andre Marette, Philip J.
