Abstract: Techniques are generally described for removal of objectionable content from video streams. In various examples, a first frame of image data comprising a two-dimensional grid of pixels is received. First data identifying at least one pixel of the first frame for obfuscation prior to display by a recipient computing device may be received. In some examples, a first segmentation map may be generated based at least in part on the first data. In some examples, pixel values of one or more pixels of the first frame of image data may be changed according to the first segmentation map. In some examples, the first frame of image data may be sent to a recipient computing device.

Abstract: Techniques for improving routing of natural language inputs, of a natural language processing (NLP) system, are described. A natural language input may be routed based on the device that captured the natural language input. A device manufacturer, hospitality provider, business, etc. may cause the NLP system to generate a skill component specific to the device manufacturer, hospitality provider, business, etc. Thereafter, when a natural language input is received from the device, the NLP system may route the natural language input to the device manufacturer-, hospitality provider-, business-, etc.-specific skill component for processing.

Abstract: Systems and methods are described herein for performing a verification process. In some embodiments, video streams may be exchanged between two devices via a first network connection. Additionally, an out-of-band connection can be established between the two devices. A degradation in the first network connection may be detected. In response to the detection, the first device may be configured to identify one or more key frames from the video stream. The key frames can be identified due to the inclusion of information indicative of the identity of the user of the first device (e.g., a representation of the user’s face and/or an identity document such as a driver’s license). The key frames are transmitted via the out-of-band connection with a higher quality resolution than the resolution utilized by the video stream. The first user’s identity may be verified using the key frames despite the degradation of the first network connection.
