Abstract: A depth camera assembly (DCA) determines distances between the DCA and objects in a local area within a field of view of the DCA. The DCA projects a series of sinusoidal patterns into the local area DCA and captures images of the sinusoidal patterns via a sensor. The DCA determines a distance between the DCA and locations in the local area based on a phase shift each of the sinusoidal patterns captured by each pixel of the sensor. Initially, a calibration offset is determined for each pixel of the sensor by emitting the sinusoidal patterns onto a target at a predetermined distance from the DCA and using phase shifts for a pixel and the predetermined distance to determine the pixel's calibration offset.

Abstract: An online system uses a model to detect violations of policies enforced by the online system for content uploaded to the online system by users for viewing by other users. The online system trains the model in multiple stages. To train the model, the online system obtains a set of training content items, with each content item of the set labeled with both a policy violated by the content item and a source of the content item, which acts as a proxy for a sub-category identifying a way in which the content item violated the policy. In the first stage, the online system trains the model using the set of training content items. In a second stage, the model of trained to predict policy violations from content items that are not labeled with a source. For example, the second stage is performed by freezing earlier layers in the model.

Abstract: A depth camera assembly (DCA) determines distances between the DCA and objects in a local area within a field of view of the DCA. The DCA projects a series of sinusoidal patterns each having different wavelengths into the local area DCA and captures images of the sinusoidal patterns via a sensor. Optical filters configured to pass different wavelengths of light are positioned within the sensor to form regions including adjacent pixels. Hence, pixels in a region capture light having a wavelength passed by an optical filter corresponding to the region. If the DCA projects sinusoidal patterns having different wavelengths at different times, the sensor is gated with an illumination source so regions of the sensor capturing light having a specific wavelength capture light while the illumination source emits the specific wavelength and not while the illumination source emits other wavelengths.

Abstract: An online system determines a quality of content provided by third party systems for distribution to users. The online system analyzes URL's posted within the online system by content providers to determine the quality of content of the webpages obtained by accessing the URLs. For each URL, the online system receives an original markup language document and a copy of the markup document obtained by applying a content filter. The online system extracts features from both markup language documents. The online system provides the extracted features to a machine learning based model to generate a content quality score. The online system categorizes the URL as having high quality content or low quality content. The online system restricts distribution of content items including URLs to websites with low quality content.

Abstract: Determination of an acoustic filter for incorporating local effects of room modes within a target area is presented herein. A model of the target area is determined based in part on a three-dimensional virtual representation of the target area. In some embodiments, the model is selected from a group of candidate models. Room modes of the target area are determined based on a shape and/or dimensions of the model. The room mode parameters are determined based on at least one of the room modes and the position of a user within the target area. The room mode parameters describe an acoustic filter that as applied to audio content, simulates acoustic distortion at the position of the user and at frequencies associated with the at least one room mode. The acoustic filter is generated at a headset based on the room mode parameter and is used to present audio content.
