摘要： A location brokerage system is described herein. A plurality of computing devices that are configured to output data that is indicative of a geographic location of a user are registered with the location brokerage system, and a plurality of location-based applications are registered with the location brokerage system. The location brokerage system collaborates with the computing devices to obtain location data pertaining to the user that satisfies requests for location data from the location-based application while enforcing operating restrictions/parameters imposed by the user and/or the location-based applications.

摘要： A perceptual mechanism for residue selection in a video encoder may be provided. The mechanism may comprise a method, system, or device for receiving video frames comprising pluralities of pixels. For each video frame, a sensitivity threshold may be determined for each pixel of a previous video frame. The pixels of the video frame may compared in turn to the pixels of the previous video frame to determine a residue value. The residue value may be compared to the sensitivity threshold such that when the residue value is less than the sensitivity threshold, the pixel data in the video frame may be zeroed out prior to encoding the video frame for transmission.

摘要： Embodiments are configured to provide video conferencing functionality including using pre-processing and/or post-processing features to provide a video signal, but the embodiments are not so limited. In an embodiment, components of a video conferencing system can operate to provide a video signal based in part on the use of features of a pre-processing component and/or post-processing component. In one embodiment, a video conference device can include a pre-processing component and/or post-processing component to that can be used to compensate for bandwidth constraints associated with a video conferencing environment.

摘要： Various systems and methods for detecting risk conditions in a physical workspace. An apparatus can include an interface to receive smart sensor signals from at least one autonomous mobile entity (AME) in the physical workspace. The apparatus can also include processing circuitry coupled to the interface to detect a risk condition associated with the at least one AME, based on the smart sensor signals, relative to a user device associated with a human present in the physical workspace. The processing circuitry can also detect a direction of the risk condition relative to the user device and cause a notification to the first user device. The notification can indicate the direction of the risk condition relative to the user device. Other systems, methods and apparatuses are described.

摘要： A low complexity block-based, no-reference objective blockiness metric is provided that may be combined with other artifact metrics to measure overall quality of received video stream in a video conferencing application such that measures can be taken at the transmitter or in post-processing to enhance video quality. Prior knowledge of the blockiness boundaries may be used to reduce number of computations in determining the blockiness of a particular video frame.

摘要： Real-time video processing functionality may be provided using pre-processing and/or post-processing features to provide a video signal. Components of a real-time video processing system may operate to receive a real-time video signal. The real-time video signal may be downscaled based in part on the use of features of a pre-processing component applying a downscale polyphase filter that may be used to compensate for bandwidth constraints associated with a real-time video conferencing environment. The downscaled real-time video may be communicated across a network, such as the Internet. Upon receipt of the downscaled real-time video, the downscaled real-time video may be upscaled based in part on the use of features of a post-processing component applying an upscale polyphase filter.
