Based on the sharing features of a variety of license plates (LP), the vertical edge was first detected by sobel color edge detector. Then, some approaches were adopted to adaptively remove the invalid edge regarding the characteristics of edge grayscale jump and edge density, so that the regions having features of LP were preserved. Next, by edge density(More)

License plate recognition system (LPRS) is the hard core of the intelligent traffic system. In this paper, license plate (LP) frame was captured from video image sequences by background-difference, and an improved Kalman filter method was adopted to update the background. By means of mathematical morphology (MM) and edge characteristic analysis, LP(More)
In multiplatform cooperative engagement, sensor measurements usually cannot arrive at the fusion center according to detection time because of the delay for communicating time. To solve an out-of-sequence measurements filtering problem, to improve the tracking performance and to reduce the computation cost, an improved particle filtering algorithm based(More)
In order to eliminate the influence of incomplete sample data in fault diagnosis, Bayesian theorem is used for the design of Petri nets diagnostic model. Firstly, the concept about probability Petri net is defined. It can calculate the occurred probability of the absent datum based on Bayesian theorem from the detected attributes. Secondly, for the(More)
With the increasingly serious energy crisis and environmental pollution, the short-term economic environmental hydrothermal scheduling (SEEHTS) problem is becoming more and more important in modern electrical power systems. In order to handle the SEEHTS problem efficiently, the parallel multi-objective genetic algorithm (PMOGA) is proposed in the paper.(More)
