License Plate Recognition Based on Transform Coding and Neural Network

A method of vehicle license plate recognition utilizing Karhunen-Loeve(K-L)transform is provided.The transform is used to extract features from a mass of image templates,to describe high-dimensional images with low-dimensional ones,and moreover,to implement data compression and play down complexity of the neural network.With the character to reduce eigenspace dimensionality of K-L transform and the ability to map data of BP network,the method does effectively in recognizing license plates.     

Markov Model for Packet Scheduling in the Transmission of Streaming Media

The difficulties in the transmission of streaming media are analyzed, the packet scheduling on the streaming media server is studied. A Markov model is proposed under the effect of the complex dependency among the streaming media packets and the parameters of the transmission channel. On the basis of the Markov model,a policy is made to queue the streaming media packets in the sending buffer by using the iteration method, which can optimize the playback quality under the lack of the channel bandwidth.

Service Model for Multi-Provider IP Service Management

In order to solve the problems associated with Internet IP services management, a generic service model for multi-provider IP service management is proposed, which is based on a generalization of the bandwidth broker idea introduced in the differentiated services (DiffServ) environment. This model consists of a hierarchy of service brokers, which makes it fit into providing end-to-end Internet services with QoS support. A simple and scalable mechanism is used to communicate with other cooperative domains to enable customers to dynamically setup services connections over multiple DiffServ domains. The simulation results show that the proposed model is real-time, which can deal with many flow requests in a short period of time, so that it is fit for the service management in a reasonably large network.

Research of Extracting Data from HTML Web Pages Automatically

In order to use data information in the Internet,it is necessary to extract data from web pages.An HTT tree model representing HTML pages is presented. Based on the HTT model, a wrapper generationalgorithm AGW is proposed. The AGW algorithm utilizes comparing and correcting technique to generate thewrapper with the native characteristic of the HTT tree structure. The AGW algorithm can not only generate thewrapper automatically, but also rebuild the data schema easily and reduce the complexity of the computing.
