The present invention discloses a license plate recognition system by utilizing spatial-temporal search-space reduction and method thereof. The license plate recognition system can selects a pixel with character edge feature from the inputted image and a plurality of candidate regions from the image; and detect if the candidate region of the inputted image has been appeared in a preceding image. Then the recognition system in the present invention separates the candidate region into a plurality of blocks, calculates the repeated block based on a current image and a preceding image, and determines whether the candidate region is repeated according to the repeated block. Thus, by discarding the repeated regions, the license plate recognition system in the present invention can avoid redundant calculation and improve the efficiency and performance for recognition of real plate character in the image.

This invention provides a context-aware search engine that communicates with users having a particular location at a particular time within a tessellated network of geographically spaced-apart communication nodes, typically wireless nodes / access points (APs). Based upon the user's location and time, the search engine delivers relevant site-specific information germane to that user's place and time. In an illustrative embodiment, the search engine correlates the address of the node within which the user is located when making a query to the engine via a wireless device such as a laptop computer, PDA or cellular telephone. The time of the query is also accounted for. The query causes the search engine to focus its database search (from a large array of information resources indexed by the search engine and accessible thereby) on those informational items / web sites that fit the appropriate place and time of the user. In particular wireless nodes are viewed as spatial aggregation units (such as polygons) of demarcation in an urban or other densely settled environment (e.g. a university campus, institution, etc.) to identify and characterize the physical environment of the information-seeker.

Disclosed is a method for providing information about multimedia contents in a multimedia service system. If a mobile communication terminal receives a request for content information from a user while reproducing received multimedia data according to a VOD service, the mobile communication terminal provides information related to a content request time to a content information providing server.

The method comprises the following stepsof 1) determining an electrical topological structure of the hybrid power transmission line MN; 2) acquiring the motion time of traveling waves on a section line according to the length and motion wave speed of each section line; 3) according to fault traveling wave information acquired by traveling wave distance measuring devices at the two ends of the line, adopting wavelet transform to detect and identify the moment when the fault traveling wave moves to each bus measuring end for the first time so as to obtain a time difference when the traveling wave arrives at the two ends of the bus, and calculating t1 an t2 according to formulas by combining movement time of the fault traveling wave on the whole power transmission line; and 4) starts comparing from the end M of the bus, judging that the fault position is behind the xj1 section when t1>deltat1, and judging that the fault position is on the xd1 section when deltat1<t1<deltat1+deltat2, thus calculating the fault position. The method can be used to identify the initial traveling wave of a fault more accurately, and effectively solve the problem in fault distance measurement of the cable and overhead line hybrid power transmission line of the power system.

The user entity preference model is used to order notifications based on predicted relevance. Additionally, the user personal entity preference model and implicit responses of user are used to decide timing and frequency of notifications.

A derived disparity vector is determined based on spatial neighboring blocks and temporal neighboring blocks of the current block. The temporal neighboring blocks are searched according to a temporal search order and the temporal search order is the same for all dependent views. Any temporal neighboring block from a CTU below the current CTU row may be omitted in the temporal search order. The derived DV can also be used for predicting a DV of a DCP (disparity-compensated prediction) block for the current block in the AMVP mode, the Skip mode or the Merge mode. The temporal neighboring blocks may correspond to a temporal CT block and a temporal BR block. In one embodiment, the temporal search order checks the temporal BR block first and the temporal CT block next.

Efficient temporal search range predication for motion estimation in video coding is provided where complexity of using multiple reference frames in multiple reference frame motion estimation (MRFME) can be evaluated over a desired performance level. In this regard, a gain can be determined for using regular motion estimation or MRFME, and a number of frames if the latter is chosen. Thus, the computational complexity of MRFME and / or a large temporal search range can be utilized where it provides at least a threshold gain in performance. Conversely, if the complex calculations of MRFME do not provide sufficient benefit to the video block prediction, a smaller temporal search range (a less number of reference frames) can be used, or regular motion editing can be chosen over MRFME.
