This paper presents an intelligent video surveillance system. The system is composed of one or more nodes flexibly according to the application scenarios such as private properties banks and museums. Each node is an autonomous vision-based device capable to perform intelligent tasks. It is able to digitize and compress the acquired analog video signals in MPEG-4 standard and then transmit the compressed video stream to the control center. At the same time the node makes use of a statistical approach for real-time detecting moving object and online alarm generation to enable a single human operator to monitor activities over a complex area using a distributed network of active video sensors. The node is implemented on a platform with high performance to ensure that the algorithm is able to run in real-time. Applications demonstrate that the intelligent system has an excellent performance in many scenarios to help people make decisions more accurately and rapidly. 2010 IEEE.

The guiding principle and composition of CyberCar based on machine vision was introduced. Applying IM sequence signals as input response signals and least squares method to establish the dynamic equation for CyberCar steering system by system identification experiments firstly and then combined with the preview kinematics model and two-degree steering dynamic model of vehicle. Therefore it can trace the path steadily and reliably. 2008 IEEE. the steering control mathematics model based on preview kinematics for CyberCar was established. And then the switching hyper plane is designed by applying the optimal control theory during the change of the curve curvature radius is little the curve tracking of the intelligent vehicle is carried out by adopting sliding variable structure controller. Aim at the parameter uncertainty of tire a vehicle steering system uncertain model was founded and analyzed. A H optimal controller is designed with the method of H control theory to solve the problem about model uncertainty. The simulation and experiment results show that the controller designed by the proposed method has good robustness and adaptability

The first impression of any building to a person is its exterior and decoration therefore at the same time and therefore the quality of decoration project shows the more important position in building project. A lot of projects produce quality problem because of the material color difference how to grasp and control the color change of building materials the color difference problem laying stone materials is also studied in this paper which exists universally at the common project and carry out color quantification and the solution scheme has been given using this system. and is often found at the high-grade decoration it has the very important meaning. According to the color theory a computer vision system used in color quantification measurement is established the standard illuminant A is selected as the light source. In order to realize the standardization of color evaluation the mutual conversion between RGB and XYZ color space is studied which is realized by the BP network. According to the colorimetry theory the computer program is compiled in order to establish the software system and realize the color quantitative appraisement in whole color gamut. LCH model is used at quantifying the color of building materials and L*a*V model is used at comparing the color change. If the wooden floor is selected and laid improperly during family fitment it is easy to present "flower face". The color also arises greater discrepancy using the laths of same tree. We can give the laying scheme using the color quantification system
