Bayesian theory provides a good framework for integrating prior knowledge and maximum likelihood estimation. Bayesian based particle filtering technology has been proven to be successful for non-linear and non-Gaussian estimation problems and effective for solving tracking problems. Within methods of this class, tracking is modeled by a state-space time series estimation problem, which is solved using a sequential Monte Carlo estimation method.

视觉跟踪是实现智能监控的关键技术，作为计算机视觉研究领域的核心课题之一，融合了图像处理、模式识别、人工智能、自动控制以及计算机等若干领域的先进技术，并在军事视觉制导、视频监控、机器人视觉导航、医疗诊断以及气象分析等方面都有广泛的应用。

Rice moisture content can be controlled by use of different consistency salt and acidliquor,the method of preparing different moisture contents rice sample also be studied and adopted.Such as, temperature humidity preservation box used in testing mechanical physical properties ofrice kernel, tensile and bending experiment device which can be used on rice samples. Configureddark box, CCD photography, image-taking system, pre-experiment to forcast mechanical physicalproperty and moisture transfer property, from which we can know that distance of elastic modulusand passion ratio in tensile process test is not big when renitency strength is much larger thanresist-pull strength, tensile test can be replaced by bending test to research tensile property ofrice, because tensile test is hard to do, experiment research methods and feasibility werediscussed, and suitable humid stress field experiment research plan ere made.

研究、采用了合适的盐溶液及不同浓度的酸溶液调节稻米含水率、制取不同含水率稻米试样的方法；研制了测量稻米材料机械物理特性时使用的保温保湿箱、适用于稻米试件使用的拉伸和弯曲试验装置；配置了暗箱、CCD摄像机、竖直与水平摄像装置及计算机图像采集系统等；进行稻米机械物理特性和水分传递特性的各种预备试验，得到：稻米的抗拉强度远小于抗压强度而拉压时的弹性模量、泊松比相差不大，稻米籽粒的拉伸试验难度极大，成功率很低，可以用籽粒的弯曲试验代替拉伸试验研究籽粒材料的拉伸特性；探讨试验研究方法及其可行性，制定了合理的稻米湿应力场试验研究方案。

This essay introduced the method and the empirical results of run test, Dickey-Fuller test and variance ratio test on the efficient market hypothesis. Furthermore, reviewed the volatility test method and empirical result on the EMH which relative to the tests based on stock market return.

摘 要：介绍了市场有效性假定的游程检验，DF检验以及方差比检验的方法和相关实证研究的结果，与以上基于股票市场收益的市场有效性检验相对应，对市场有效性假定的波动性检验方法以及实证结果进行了述评。

We can found that China stock market is not completely weak effective by auto-correlation test, runs test, unit root test and variance ratio test. The TT-kyle model is derived from kyle model by adding weak effectiveness and irrational factor. This chapter describes impact of weak effectiveness and irrational factor on the trading volume and price. The fifth part analyses the relationship between the transaction duration and insider trading.
