    摘要: A method and apparatus for deblocking of reconstructed video are disclosed. In one embodiment, the method divides a block boundary into two sub-boundaries and separates lines or column across the sub-boundaries into two groups. The deblocking filter decision for each group is determined based on the lines or columns in the respective group. In another embodiment, the method divides block edges of blocks in the LCUs into two edge groups, where the first edge group corresponds to horizontal block edges between two LCUs and the second edge group corresponds to remaining block edges not included in the first edge group. The number of lines processed by a vertical filter in the first edge group is less than the number of lines processed by a vertical filter in the second edge group. Accordingly, a system embodying the present invention has reduced storage requirement.

    摘要: A method and apparatus for improved deblocking filter are disclosed. In one embodiment according to the present invention, determining the non-zero transform coefficients existence for a PU-only boundary is skipped and therefore the deblocking filter for PU-only boundary is eliminated if the condition of boundary strength equal to 1 is not fulfilled to avoid unnecessary deblocking. In another embodiment of the present invention, three gradients are determined for two pixel lines and filter ON/OFF decision is made based on the three gradient values of the two pixel lines. One aspect of the invention is related to filter strength selection between strong and weak filters. According to one embodiment, the filter strength selection is based on various gradient values of a pixel line across the block boundary. Another aspect of the invention is related to the weak filter.

    摘要: A system and method for determining the magnetic sensitivity of a Hall-effect switch through the use of a variable powered DC electromagnet having a permanent magnet attached to it. In use the electromagnet is placed in contact with a Hall-effect switch component and the DC voltage varied until a detector determines the Hall-effect switch has been triggered. The electromagnet is then moved to be in contact with a probe connected to a Gauss meter to determine the magnetic sensitivity of the Hall-effect switch.

    摘要: A method for extracting an image representing textual information from a video sequence includes the following steps. First, receiving a sequence of video frames, each including an image of textual information. Then, locating the textual information in each frame of the video sequence to form a stack of text arrays, each array containing data representing substantially only the textual information. Finally, extracting a single textual image array representing the image of the textual information from the stack of text arrays. Apparatus for extracting an image representing textual information from a video sequence includes a source of a video sequence having a plurality of frames, each containing an image of the textual information; and a processor, coupled to the video sequence source, responsive to all of the plurality of frames, for generating a single array representing an image of the textual information.

    摘要: A multimedia search apparatus and method for searching multimedia content using speaker detection to segment the multimedia content. The multimedia search apparatus receives a search request from a user device. The search request identifies the target speaker for which the search is to be conducted. Based on the search request, the multimedia search apparatus retrieves multimedia content from a multimedia database. The multimedia search apparatus retrieves models, such as Gaussian Mixture Models (GMMs), from a model storage device, corresponding to the target speaker and background data. Based on the retrieved models, the multimedia search device searches the multimedia data of the multimedia content and segments the multimedia data. The segments are identified by calculating an average normalized score for a block of frames of the multimedia data and determining if the average normalized score for the block of frames exceeds one or more predetermined thresholds.
