摘要： A method (300) and apparatus (120) are disclosed that authenticate a user of a mobile device (120) with motion sensors (210). During a learning session (500), the user initializes the mobile device (120) by providing (510) a motion sample. The mobile device (120) extracts (520) motion features that are unique to the user and converts (530, 550) them to parity bits (340) and to a password shadow (370). During a recognition session (300), a motion pattern is gathered (310) from the user moving the mobile device (120) as if it were a virtual pen. The mobile device (120) then uses the stored parity bits (340) to correct (330) small differences between motion patterns exhibited by the same user at different times. The mobile device (120) converts (350) the corrected motion pattern into a motion password that is compared (360) with the stored password shadow (370). A user is authenticated only if the two values coincide. The system erases (420) the generated motion password.

摘要： A number of uplink transmissions from multiple remote devices (102, 104, 106) is received. The remote devices correspond to a single network node (112), and each of the uplink transmissions corresponds to a request for content. A subset of remote devices whose uplink transmissions correspond to requests for common content is identified and a Quality of Service (QoS) level corresponding to the number of remote devices in the identified subset is determined. The common content is transmitted to the single network node at the determined QoS level.

摘要： A system (100) and method (200) for efficient video adaptation of an input video (102) is provided. The method can include segmenting (210) the input video into a plurality of video shots (142) using a video trace (111) to exploit a temporal structure of the input video, selecting (220) a subset of frames (144) for the video shots that minimizes a distortion of adapted video (152) using the video trace, and selecting transcoding parameters (122) for the subset of frames to produce an optimal video quality of the adapted video under constraints of frame rate, bit rate, and viewing time constraint. The video trace is a compact representation for temporal and spatial distortions for frames in the input video. A spatio-temporal rate-distortion model (320) provides selection of the transcoding parameters during adaptation.

摘要： A system and a method for progressive queries, which are a sequence of queries for visual search of an image, sent from a sender to a receiver of a communication network, are disclosed. Queries based on a set of feature points and their associated locations of an image may be selected in sequence. A sender sends a first query to a receiver, wherein the first query comprises a number of feature points which is a subset of the set of feature points of the image invariant to rotation and scaling in creating the image. The sender receives a feedback from the receiver, wherein the feedback is generated by the receiver based on searching an image repository using information from the first query. The sender then decides whether there is a match of the image in the image repository based on the received feedback.
