Abstract: Systems, methods, client devices, and non-transitory computer-readable media are disclosed for utilizing video data and video processing data to enable shared augmented reality scenes having video textures depicting participants of video calls as augmented reality (AR) effects during the video calls. For instance, the disclosed systems can establish a video call between client devices that include streaming channels (e.g., a video and audio data channel). In one or more implementations, the disclosed systems enable the client devices to transmit video processing data and video data of a participant through the streaming channel during a video call. Indeed, in one or more embodiments, the disclosed systems cause the client devices to utilize video data streams and video processing data to render videos as video textures within AR effects in a shared AR scene (or AR space) of the video call (e.g., to depict participants within the AR scene).

Abstract: In one embodiment, a method includes receiving, from a client system associated with a user, a first user request that includes a reference to a target object and one or more of an attribute or a relationship of the target object. Visual data including one or more images portraying the target object may then be accessed, and the reference may be resolved to the target object portrayed in the one or more images. Object information of the target object that corresponds to the referenced attribute or relationship of the first user request may be determined based on a visual analysis of the one or more images. Finally, responsive to receiving the first user request, the object information of the target object may be stored in a multimodal dialog state.

Abstract: A user provides video data to an online system for presentation to additional users of the online system. Additionally, the user provides information to the online system identifying positions in the information capable of presenting supplemental content items, which may be sponsored, and may provide information describing a context of the video data at the various positions capable of presenting the supplemental content items. For example, the information identifies one or more times within the video data at which an advertisement is capable of being presented via the video data. Based on the information provided by the user, the online system selects supplemental content items for presentation via the video data at the identified positions and presents the selected supplemental content items to additional users viewing the video data at the identified positions.

Abstract: In some embodiments, a computer-implemented method includes obtaining a without-eyeglasses face scan of a subject, the without-eyeglasses face scan being a three-dimensional (3D) model of a face of the subject without eyeglasses; obtaining a with-eyeglasses face scan of the subject, the with-eyeglasses face scan being a 3D model of the subject with eyeglasses; and using the without-eyeglasses face scan and the with-eyeglasses face scan to place a 3D eyeglasses model on a face model of the subject. In some embodiments of the computer-implemented method, the 3D eyeglasses model is placed on the face model of the subject using frame placement information generated using the without-eyeglasses face scan and the with-eyeglasses face scan.
