    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 number of uplink transmissions from multiple remote devices is received. The remote devices correspond to a single network node, 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: An object detection algorithm that generates a two-layer Gaussian Mixture Model (GMM) during a training session, and subsequent to the training session, uses the two-layer GMM to perform face detection. No labeling of local features is needed. The only input that is provided by a user is the setting of a few global parameters for the image being captured during the training session, such as, for example, the person's facial pose.

    摘要: A video encoding system (200) provides content adaptive rate control that includes a visual analyzer (208) utilizing at least one visual analysis tool for processing a video frame to provide visual information describing the video frame. An encoder (204) generates encoding status information relating to the video frame being processed. A rate controller (206) is responsive to the encoding status information generated by the encoder (204) and the visual information generated by the visual analyzer (208) to generate a rate control adjustment signal. The encoder (204) is responsive to the rate control adjustment signal for encoding the video frame.

    摘要: A search system (200) for a database (224) including records having a multiple disparate types of media is provided. The search system supports queries, that include different types of search criteria, including content based retrieval search criteria. A fuzzy logic method (400) is provided for effectively combining the results of different types of search criteria. The fuzzy logic method also allows confidence levels entered by the user for search criteria to be considered in combining results. Retrieval relevance values for documents for at least some search criteria are used in the fuzzy logic method. For content based image retrieval searches, the retrieval relevance values are computed by mapping a distance between quantitative characterizations of a search basis image, and other images into a finite range.

    摘要: Methods and systems for a multimedia queue management solution that maintaining graceful Quality of Experience (QoE) degradation are provided. The method selects a frame from all weighted queues based on a gradient function indicating a network performance rate change and a distortion rate caused by the frame and its related frames in the queue, and dropping the selected frame and all its related frames, and continues to drop similarly chosen frame until a network performance rate change caused by the dropping frame and its related frames meets a predetermined performance metric. A frame gradient is a distortion rate divided by a network performance rate change caused by the frame and its related frames, and a distortion rate is based on a sum of each individual frame distortion rate when the frame and its related frames are replaced by some other frames derived from remaining frames based on a replacement method.

    摘要: A one-piece core-making technique used in producing railway truck bolsters and side frames, which includes the following steps: 1. After scraping the top of a core box, applying a shaped top mould (11), which is precisely located, from top to bottom. 2. Press or slightly hit the top mould (11) to make sure the top mould covers/caps the scraping surface. 3. Keep pressing to make sure that the flat scraping surface was pressed to a required curved shape, like the shape of the top mould (11). 4. Last, it will become a one-piece core with a partially integrated inner cavity section. The one-piece core made by this technique has a smooth surface. This technique also can improve the internal quality of the product and ease work intensity.

    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.
