this paper presents a new Line Enhance Active Contour model (LEAC model) to detect the flame front boundaries from high speed Planar Laser Induced Fluorescence (PLIF) images. The model first enhances the crack region and the gradient of flame front by the Line Enhance Filtering algorithm, and then extracts flame front boundaries and crake edges from the enhanced PLIF images using the CV model. We compared the LEAC model with the classical CV model on different PLIF images. Experimental results show that our model can detect the flame front accurately, and it has good performance on detecting the exact edges of long and narrow crack regions, where the classical CVmodel can not detect completely. Moreover, it is insensitive to image noise and curve initialization.

RS is a popular FH code whose chaotic features of frequency sequence is analyzed in this article and such a conclusion is achieved that RS code is of chaotic features in terms of frequency sequence. According to this conclusion, a method of FH prediction about the degree of incidence is suggested based on the phase space reconstruction of chaotic system. It is more accurate than the chaos prediction method of the nearest point in phase space based on the Euclid distance.

To improve the efficiency of blade repair, a reverse engineering-based geometry reconstruction method is developed for the normal model creation of a broken blade. The key techniques involved are including the digital measurement of broken blade, point cloud pre-processing, three dimensional models and so on. After the point cloud pre-processing, the segmentation extracts the damaged region from point cloud by a 4D Shepard surface based curvature estimation method. Bezier curve is used to construct the extracted boundary points. Bezier surface is reconstructed by the extracted points and is used to broken space subdivision. At last, a geometry model is built for the preparement of the laser forming repair.

the characteristics of the nodes’ high-dynamic and long transmission delay between the satellites and terrestrial station lead to the difficulty in managing the satellite network. So this paper proposes a new dynamic-layered management architecture based on the researches of the traditional policy-based network management architecture. In the new architecture, domain policy decision point(Domain PDP) and local policy decision point(local PDP) are added between policy enforcement point(PEP) and traditional policy decision point(PDP). Domain PDP and local PDP are dynamically deployed in the sub-management stations and the satellite agents with management functions. Simulation results show that the new architecture reduces the amounts of the communication between terrestrial station and satellite agent which makes the network management efficiently.

The purpose of moving targets tracking is to determine the trajectories of moving targets, the key of which is to establish the corresponding relationships between the detected prospect targets and the tracked moving targets. The established corresponding relations are equivalent to the matching problem of target features in consecutive image frames. In the paper, Kalman filter is used as the motion model of the targets. The recursive filtering method is adopted to calculate and predict the location of moving targets. Through the experiment, the results show that the algorithm not only track well the moving targets, but also can effectively overcome the obstacles in the process of tracking and so on.

The paper researches the issue that fundamental matrix is recovered in images. Firstly, the corners are detected by Harris operator, and matches cross-correlation corners. According to the definition of polar equation, the polar of feature point must pass corresponding point in matching images. Then, to extract correctly matching points and eliminate error by the criterion which is the distance between corner and corresponding polar. At the end, More precise fundamental matrix is got by Particle Swarm Optimization according to the target function that is residual error of polar equation. Experimental result proves that interrelated arithmetic is effective.
