摘要： Sketch and tagging based image search may include receiving a sketch query input and identifying an object in a desired image. The object or objects of the sketch query may be tagged with a text, and searching performed based on the objects. Certain implementations include indexing patches of the images, where the patches represent the objects. Relevant images can be returned based on the index of the patches.

摘要： Local features of retrieved images are identified and for each image, an ordered bag-of-features is created that describes the features of the image. Spatial relationships between features of an image are captured in histogram descriptors created from linear or circular projections. Using the histogram descriptors, ordered bags-of-features describing the features of the images are developed. Calibrating the ordered bags-of-features to account for spatial variance leads to spatial bags-of-features.

摘要： Sketch-based image search may include receiving a query curve as a sketch query input and identifying a first plurality of oriented points based on the query curve. The first plurality of oriented points may be used to locate at least one image having a curve that includes a second plurality of oriented points that match at least some of the first plurality of oriented points. Implementations also include indexing a plurality of images by identifying at least one curve in each image and generating an index comprising a plurality of oriented points as index entries. The index entries are associated with the plurality of images based on corresponding oriented points in the identified curves in the images.

摘要： A virtual interface application presented in augmented reality (AR) is described for controlling Internet of Things (IoT) products. The virtual interface application enables a user of a portable electronic device to activate a virtual control interface overlay on a display, receive a selection from the user using her hands or feet, and send a control signal to a nearby IoT product which executes an action in accordance with the selection. The virtual control interface is presented on the display as a virtual object in an AR environment. The virtual interface application includes a foot tracking tool for detecting an intersection between the foot location (in the physical environment) and the virtual surface position (in the AR environment). When an intersection is detected, the virtual interface application sends a control signal with instructions to the IoT product.

摘要： Described are virtual AR interfaces for generating a virtual rotational interface for the purpose of controlling connected IoT devices using the inertial measurement unit (IMU) of a portable electronic device. The IMU control application enables a user of a portable electronic device to activate a virtual rotational interface overlay on a display and adjust a feature of a connected IoT product by rotating a portable electronic device. The device IMU moves a slider on the virtual rotational interface. The IMU control application sends a control signal to the IoT product which executes an action in accordance with the slider position. The virtual rotational interface is presented on the display as a virtual object in an AR environment. The IMU control application detects the device orientation (in the physical environment) and in response presents a corresponding slider element on the virtual rotational interface (in the AR environment).

摘要： Techniques for controlling communication amongst a group of vehicles include determining whether a cellular network is unavailable or a user input indicative of a switchover request has been received, when the cellular network is available, controlling a cellular network transceiver to share information between the vehicle and one or more other vehicles of the group of vehicles via the cellular network, and when the cellular network is unavailable or in response to receiving the user input indicative of the switchover request, controlling a low Earth orbit (LEO) satellite network transceiver to share information between the vehicle and the one or more other vehicles of the group of vehicles via an LEO satellite network and not via the cellular network.

摘要： A video processing device receives video data and transmits the video to a display device at a new bit rate that is dynamically adjusted based on variable conditions. The new bit rate is adjusted, at least, by scaling the video and/or a residual image and may be adjusted utilizing compression functions, compression parameters, scale factor, frame rate, color space, and chroma sub-sampling. The display receives video at the adjusted new bit rate and decompresses the video in accordance with corresponding adjustments in the video processing device. Bit rate determination is based on variable operating conditions, display information, image quality, BER, packet error, SNR, desired level of compression, energy consumption, link congestion and display capabilities. Video may be scaled prior to compression. The video may comprise a frame and/or a slice. DPCM, H.264, AVC, transform compression and scaling may be utilized. The display may utilize intra-frame spatial prediction.

摘要： Methods are provided for using a dewaxing catalyst formed using at least two structure directing agents for production of a lubricant base stock. For example, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic production of lubricant base stocks. Additionally or alternately, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can provide improved aromatic saturation during processing of a feed for lubricant base stock production.
