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: 本实验要求编写一个计算图像直方图的程序并要求讨论直方图均衡化技术，最后对图3.8（a）进行均衡化处理。直方图是多种空间域处理技术的基础，直方图操作能有效的用于图像增强。在实验中根据直方图对应的离散函数可以编写出计算一个图像直方图的函数，直方图均衡化则是借助于直方图灰度变换实现灰度映射从而达到图像增强的目的。实验通过得到原始图像的直方图，直方图均衡化变换函数图和增强后的图像增强后图像的直方图这些实验数据来解释图像被增强的原因。-In this study requested to prepare a procedure for calculating the image histogram and asked to discuss histogram equalization technology, the last of Figure 3.8 (a) a balanced treatment. Histogram is a variety of spatial processing technology foundation, histogram operation can be effective for image enhancement. In the experiment under the histogram corresponding discrete function can be calculated to prepare an image histogram function, histogram equalization is a means of gray-scale transformation to achieve gray histogram mapping so as to achieve the purpose of image enhancement. Experiments have been the original image through the histogram, histogram equalization transformation function maps and enhanced image after image enhancement histogram of these experimental data to explain the reasons for the image was enhanced.

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.

Description: Based on a local spatial/frequency representation,we
employ a spectral histogram as a feature statistic for texture classification.
The spectral histogram consists of marginal distributions
of responses of a bank of filters and encodes implicitly the
local structure of images through the filtering stage and the global
