The liqase was positively controlled by HAI and AI-2 to some extent. The lecithinase was negatively controlled by HAI-1, and the hemolysin was negatively controlled by both HAI-1 and AI-2. Special primers of luxS gene were designed from the luxS gene sequence of V. harveyi obtained from the GenBank, and the gene was amplified from a pathogenic strain V. harveyi VIB645 by PCR. The luxS gene was cloned to a cloning vector pUC, and was sequenced. It was found that the open reading frame is 519 bp. The similarity of the luxS gene from V. harveyi VIB645 to the published sequence of V. harveyi strain in GenBank was only 90%.

In this paper, the theory, algorithm, and experiment of automatic object detection and tracking are studied in depth. It is firstly pointed out that the essential of Mean Shift method is a special Newton-Gaussian method. A new method named Fast Mean Shift is established to stretch the conservative step of Mean Shift method. The convergence and validity of this new method are proved in theory. And it is also proved that the convergence speed of Fast Mean Shift is faster than that of Mean Shift. The contrast experiments of searching the maximum possibility density of random of data sets in plane and 3D space are done. The results show that this new method can reduce the iterations greatly. A new object tracking method based on Fast Mean Shift is built to improve the object tracking performance, which is shown in the face tracking experiment with the tennis sequence provided by the Ohio State University, and the car tracking experiment with the car sequence provided by Kalsruhe University. The face trcking experiment with highly noised images show that the object tracking method based on Fast Mean Shift has strong anti-jamming ability. A new fast color object detection technology based on characteristic color is established, which use characteristic color distribution to compute the characteristic color vector of any area in an image quickly. With the high performance search method, the fast object detection is achieved. At last, using object tracker based on Fast Mean Shift and color object detector based on characteristic color with the Kalman filter, PID controller, searial communication and other technologies, automatic object detection and tracking system with control system is built. The availability and anti-jamming ability of this system are verified by some object detection and tracking tests in different scenes.
