Abstract: Methods and systems provide for providing a virtual background within a communication session using dynamic chroma key reframing. In one embodiment, a method displays a user interface including at least one video feed corresponding to a participant of the communication session. The method receives a request to enable a selected or provided virtual background using chroma keying. The method then determines a background layer of the video feed. The method also determines edges for the background layer. Next, the method crops and reframes the video feed around the edges of the background layer. The method then removes the background layer from the video feed, and adds the selected or provided virtual background to the background layer of the video feed. Finally, the method displays the video feed within the communication session.

Abstract: A data acquisition and reconstruction method and a data acquisition and reconstruction system for human body three-dimensional modeling based on a single mobile phone. In the aspect of data acquisition, the present application only uses a single smart phone, and uses augmented reality technology to guide users to collect high-quality video data input for a reconstruction algorithm, so as to ensure that the subsequent human body reconstruction algorithm can stably obtain a high-quality three-dimensional human body model. In the aspect of a reconstruction algorithm, the present application designs a deformable implicit neural radiance field. The use of an implicit spatial deformation field estimation model solves the problem that the subject has small motion in the process of collecting data with a single mobile phone; the implicit signed distance field is used to represent human geometry, which has rich expressive ability and improves the accuracy of three-dimensional human model reconstruction.

Abstract: 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.

Abstract: This document discloses a method, system, and/or software configured to provide improved color rendering of an item or scene, such as an item for sale through web sites or printed brochures (e.g., color catalogs). This improved color rendering can be provided through improved accuracy when rendering an online item, such as on a user's laptop, smartphone, or desktop computer showing a webpage. Further still, this document discloses ways in which to solve numerous problems in the field of online sales where an accurate rendering of an item, and even a customized rendering of an item to fit a buyer's intended use for the item, is desired. This document also describes ways in which to improve color renderings for a print item through use of a user's device to capture an image using the device's camera, and then display the item more accurately or congruently than it was originally displayed in print.
