  • Publication number: 20080165678
    Abstract: A network processor for processing information elements is described. Each information element is associated with a flow and comprises at least one information element segment. A policy controller stores an information element into at least one information segment storage unit within a memory, and determines whether an information element segment conforms to a predetermined quality of service (“QoS”). A traffic processor selects the information element segment for forwarding based on at least one QoS parameter. A forwarding processor forwards the selected information element segment to an egress port.

  • Publication number: 20040234105
    Abstract: An innovative method of automatic vehicle licence plate recognition is described, the vehicle licence plate recognition procedure is carried out respectively with reference to three component color red(R), green(G), and blue(B) grey level pixel maps, and then the results are reorganized. Sine the synthesized three component color R, G, B grey level pixel map is obtained by mixing R, G, B color component according to a definite proportion (for example dividing the sum of three component by 3), hence among the three component color grey level pixel maps, there must be at least one (R, or G, or B) whose contrast is better than that of the synthesized one. This most confidential one is picked out as the final result of the licence plate recognition.
