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.

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.

Duringreproduction, according to the packet number obtained by searching the EP_map by using the specified reproduction time, decoding of the encoded stream reproduced from the recording medium is controlled. It is possible to guarantee random access reproduction performed by specifying the reproduction time.

A living website is provided that autonomously and dynamically changes presentation based on engagement from users, business members, distributed devices, and, optionally, individual user preferences. The living website presentation changes with the promotion and demotion of website elements through repositioning, visual differentiation, and other means. These changes are produced by a machine rewriting of the living website code that is conditioned on the continually tracked engagement. In particular, the tracked engagement identifies the website elements that are most engaging at that time. The living website then adapts in order to presents users with this most engaging content in a manner that is immediately apparent and before them. Consequently, users spend less time searching, scrolling, or otherwise browsing a website in order to find content that is engaging and of interest to them, and more time interacting with the engaging content that is already before them.
