    摘要: A method of coding video content. The method can include, identifying a first plurality of image blocks within a picture based on at least a first image characteristic that is common to each of the first plurality of image blocks. A first image block group can be dynamically defined. At least one of the image blocks can be selected as a predictor block to predict other image blocks within the first image block group. In another arrangement, at least a first image block and a second image block can be identified within a picture. The second image block can be predicted from the first image block. A displacement vector can be defined to associate the second image block with the first image block. A value representing the displacement vector can be included within a header of the second image block.

    摘要: At least one visual significance metric is determined (12) for at least some frames belonging to an original series of frames (11). Key frames are identified (13) as a function, at least in part, of the visual significance metric. Cumulative visual significance values are then determined (14) for at least some of the frames that intervene between each pair of key frames. These cumulative visual significance values are then used to identify (15) frames of additional content interest. Various frames are then selected (16) for use in a visual summary. In one embodiment, all of the key frames and frames of additional content interest are selected for inclusion in the visual summary.

The first number of points may be locations of a set of rotation and scaling invariant feature points for the image, and the generated first vector may be a graph spectrum of a pair-wise distance matrix generated from the first number of points of the image.

    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.

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

    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: An embodiment of an apparatus to authenticate a sequence of video frames includes a process to choose intra-frames of the sequence and sample DC components thereof to produce a set of test fingerprints. To reduce a dimensionality of the test fingerprints, the DC components of the chosen intra-frames are multiplied by a projection matrix formed of eigenvectors associated with the larger eigenvalues of a covariance matrix for a library of frames. The projected test fingerprints are compared against a reference set of fingerprints for authentication. Time-stamp spacings of the chosen intra-frames are determined, and these spacings are employed to select candidate frames for authentication in the reference set of fingerprints.
