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: Technology for customized crest factor reduction (CFR) noise shaping includes dividing a frequency band into a plurality of regions, assigning a constellation goal for each region, the respective constellation goal for at least two regions being different, determining a CFR noise level for each region based on the constellation goal for the region and a target CFR noise level for the divided frequency band, creating a cancellation pulse based on scaling factors, and based on the cancellation pulse, applying a cancellation pulse signal on a per-region basis to generate transmission signals having the determined CFR noise level for each region. In examples, a first region has a first constellation goal and a second region has a second constellation goal, and a determined CFR noise level for the first region supports the first constellation goal and a determined CFR noise level for the second region supports the second constellation goal.

Abstract: An image processing system enables a user wearing a head-mounted display to experience a virtual environment combined with a representation of a real-world object. The image processing system receives a captured scene of a real-world environment that includes a target object. The image processing system identifies the target object in the captured scene and generates a representation of the target object. In some cases, the image processing system may include a graphical overlay with the representation of the target object. The image processing system can generate a combined scene that includes the target object and the virtual environment. The combined scene is presented to the user, thereby allowing the user to interact with the real-world target object (or a representation thereof) in combination with the virtual environment.
