Description: 本文提出了一种基于矢量角度的最短路径搜索算法，设计出一种类似于面向对象的数据存储结构来存储网络图中的节点及弧段对象，在最短路径的搜索上引入矢量夹角标量值做为搜索因子，充分利用了网络图中各点元素和线元素间的拓扑关系，提高了搜索的趋势性，同时还考虑了各弧段的长度值（或权值），较好的将网络图中对象的空间信息和属性信息相结合-In this paper, a vector-based perspective of the shortest path search algorithm to design a similar object-oriented data storage structure to store the network diagram of nodes and arcs object, in the shortest path search on the introduction of the vector angle between the scalar value as a search factor, make full use of the network elements in the points and lines of topological relations between elements to enhance the search trends, while also taking into account the arc length of the value (or weight), good will network map object spatial information and attribute information to combine

Description: 本实验要求使用强度变化方法对图像进行增强。图像增强的是要目标是处理图像，使其比原始图像更适用于特定应用，图像增强的方法分为两大类，空间域方法和频域方法，“空间域”一词是指图像平面本身，这类方法是以图像像素的直接处理。“频域”处理技术是以修改图像的傅里叶变换为基础的。本实验采用的对数变换和指数变换是对前一种方法的应用。-This experiment requires the use of intensity changes in methods of image enhancement. Image enhancement is to target is to deal with images, so that it more than the original image is more applicable to specific applications, image enhancement method is divided into two categories, spatial domain methods and frequency domain methods,

Description: A new approach toward target representation and localization, the central component in visual tracking
of non-rigid objects, is proposed. The feature histogram based target representations are regularized
by spatial masking with an isotropic kernel. The masking induces spatially-smooth similarity functions
suitable for gradient-based optimization, hence, the target localization problem can be formulated using
the basin of attraction of the local maxima. We employ a metric derived from the Bhattacharyya
coefficient as similarity measure, and use the mean shift procedure to perform the optimization. In the
presented tracking examples the new method successfully coped with camera motion, partial occlusions,
clutter, and target scale variations. Integration with motion filters and data association techniques is also
discussed. We describe only few of the potential applications: exploitation of background information,
Kalman tracking using motion models, and face tracking.-A new approach toward target representation and localization, the central component in visual trackingof non-rigid objects, is proposed.

Description: 提出一种新的目标表示和定位方法,该方法是非刚体跟踪的核心技术.利用均质空间掩膜规范基于特征直方图的目标表示,该掩膜引入了适合于梯度优化的空间平滑相似函数,所以可以将目标定位问题转换为局部极大值求解问题.我们利用从Bhattacharyya系数倒出的规则作为相似度量,利用mean shift procedure完成优化求解.在给出的测试用例中, 本文方法成功解决了相机移动,阴影,以及其他的图象噪声干扰.文章对运动滤波和数据关联技术的集成也进行了讨论.-A new objective and positioning method to track non-rigid body' s core technology. Standardizing the use of homogeneous space mask the characteristics of histogram based on the objectives that the mask is suitable for the introduction of gradient optimization is similar to spatial smoothing function, Therefore, targeting the problem can be converted to solve the problem of local maxima. We poured from the rules of Bhattacharyya coefficient as similarity measure, using mean shift procedure for solving optimization. give the test cases in, the method succeeded in solving the camera Mobile, shadows, and other image noise. article on the campaign filtering and data association techniques of integration were also discussed.
