    摘要: Provided are a content-based searching method and system for multimedia objects using a high-dimensional feature vector data based on a 2-level signature. The method for searching the high-dimensional data using a signature file includes calculating a first-level query signature and a second-level query signature by using the query feature vector, performing a first filtering operation to obtain a primary candidate cell group by searching a second-level signature file, and performing a secondary filtering operation to obtain a secondary candidate cell group having a high similarity in a primary candidate cell group. Accordingly, the high-dimensional data searching method and system can process a query quickly and accurately and can increase the searching accuracy by using an enhanced signature of the query feature vector.

    摘要: Provided are a network scheduler and a network scheduling method capable of effectively managing network bandwidths by selectively supporting a work conserving mode to network entities by using an improved token bucket scheme. The network scheduler selectively supports a work conserving mode to network scheduling units (NSUs) serving as network entities by using a token bucket scheme, such that the network scheduler ensures an allocated network bandwidth or enables the NSUs to use a remaining bandwidth. The network scheduler manages the NSUs by classifying the NSUs into a green state, a red state, a yellow state, and a black state according to a token value, a selection/non-selection of the work conserving mode, and an existence/non-existence of the packet request to be processed.
