In this thesis, we apply Coulomb's law and propose an external force to overcome the problem of traditional ACM that can not capture the cavities of an object. Assume that each node of a snake has its own electric charge, and the object boundary has opposite electric charge. Then object boundary will attract the nodes of the snake. This helps the contour easily to move to the object boundary.

本论文中，我们运用库仑定律的观念，提出了一个运用局部引力作为外力的方法，用以克服传统主动性轮廓模型在凹面处收敛不佳的缺点；假设物件边界带电，而主动性轮廓模型的结点带与物件边界相异之电荷，则物件边界会吸引著主动性轮廓模型各结点，使得模型曲线更容易靠近物件边界。

Clustering divides a set of physical or abstract object into several clusters that constitutes for the similar object, the object in the same of cluster are similar each other, but the object in the different cluster are dissimilitude each other.

Digital image processing technology,the present reseach level about image alarm system is to separate eyewinker from monitoring image,and to judge whether the eyewinker is harmful according to the size of the area of object,this method is imprecise and suspectable.The image recgnition alarm system isan apply on image processing technology.when a foreign object enter monitoring place,we will segment、measure object,and analysis、judge through proportion characer or invariant monent.the result of the parameter will decide whether the eyewinker is harmful,if the object is harmful ,system will auto-startalarm device.

而本设计的主要特点是基于了数字图像处理技术，目前传统图像报警系统的研究水平是将异物从监控图像中分离出来，然后依据异物面积的大小来判断异物是否有害，它对异物有害的判断十分不准确，这种判断结果的有效性是很值得怀疑的；针对于这些弊端，本课题在数字图像处理技术上的应用是对监控场所进行全景监控，如有异物进入，对异物进行分割、测量，从不同的角度进行了分析和判断，进而决定异物是否有害，若满足场景所规定的有害条件，则启动报警装置，发出报警信息。

If part of an object's value is in another object, the hash code computed for the object's should be partially based on the other object's hash code.

如果一个物体的一部分的价值是在另一个对象，计算散列代码的对象应该是部分基于其他对象的散列代码。

Postmodernism shows the inclination of inaction in their viewpoints to theory, life and art :On theory, they oppose constructing theory system, oppose pursuing the deep essential, while advocate "cutting away the deep mode",to stay on the surface; On liff, they oppose controlling the object and advocate that the subject should surrender to the object world, discarding the plan and in ter tion to control the object, While should imitate and follow the object; On art, the postmodern writers no longer undertake the mission of transmitting the truth, no longer pretest alienation, but sink in the earthy joyousness, going to absurdity.

后现代主义之所以能够与轴心时代的三位思想家达成这种一致，是因为当今人类重新面临了、认识了人类在相对弱小的轴心时代所遭遇的困境——今天世界的强大又重新造成了人的弱小和无能为力，人类又重新进入困境时代，常有废墟、荒原之感的后现代主义就是这种困境时代的反映。

The proposed method first uses common subtractive clustering locating method to acquire video object position and moving object number of each frame. Then, the proposed algorithm uses fuzzy C-means clustering algorithm to further cluster the moving object foreground pixel samples. Finally, matrix analysis theory for calculating eigenvalues and eigenvectors of covariance matrix is applied to compute the object scale and orientation parameters.

该算法在减法聚类算法预定位目标位置及获得目标个数的基础上，进一步采用模糊C均值聚类对目标前景样本进行归类，最后通过对目标前景样本协方差矩阵特征值和特征向量的分析获得目标的尺度及方向参数，从而实现对视频运动目标的定位。

A frame image of a video frequency sequence is read into a postpositional memory zone, and staring position and size information of a tracked object is obtained in the frame, then distribution statistical information of a target signature is extracted to build a gauss mixed model as an object template, a mean vector and a covariance matrix in gauss mixed distribution are used to describe the position and the size of the object, then the next frame image of the video frequency sequence is read into the postpositional memory zone. In a new frame video frequency image, a parameter estimation method is used to obtain object gauss mized model parameters in the current frame in iterative computation and find candidate template similar to the object template, and the final model parameters obtained in iteration are used to update the tracking window for realizing self-adaption of the tracked window.

将视频序列的一帧图像读入缓存区，获得该帧中被跟踪目标的初始位置和尺寸信息，然后提取目标特征的分布统计信息建立高斯混合模型作为目标模板，用高斯混合分布的均值向量和协方差矩阵描述目标的位置和尺寸，再将视频序列下一帧图像读入缓存区，在新一帧视频图像中利用参数估计方法迭代计算当前帧中目标高斯混合模型参数找到与目标模板最相似的候选模板，利用迭代得到的最终模型参数更新跟踪窗口实现跟踪窗宽的自适应。

Based on the meaning of object state in tracking theory, a novel representation for object state is proposed, which differs from traditional one with only locomotors state. In this thesis, model parameters may also represent the object state in according to different situations. Thus, the localization and characters of object are filtered synchronously, which accelerates the matching and tracking speed in real-time tracking system, especially for complicated object. In summary, this thesis studies the methods of template obtaining, updating and matching, etc.

从跟踪理论的目标状态所表示的意义出发，提出了将目标模型参数与运动参数同时作为目标状态进行滤波的方法，改变了传统方法中只利用目标运动状态的情况，在确定目标位置的同时能够匹配目标轮廓或其他特征，对于复杂的目标，可以快速鲁棒的完成视频帧中的模板匹配和跟踪。
