The algorithm tracks the changing rate of each coordinate transformation parameter through Kalman filter to facilitate better prediction of the initial searching point. More importantly, the powers of the noise models of the Kalman filter are effectively estimated online rather than making artificial assumptions on their values. The algorithm can hence adapt to various target motions and searching precisions in a real-time manner without any manual intervention.

该算法通过对坐标变换参数的变化率进行Kalman滤波来更好地预测初始搜索点；更重要的是，该算法有效地在线估计Kalman滤波器中的模型噪声功率，而非先验地对它们的取值做出假设，因而能够在没有任何人工干预的情况下动态地根据不同的目标运动状况和搜索精度进行实时调整。

In this paper, we propose a new approach to recognize occluded objects. The information of the magnitude of the local extreme of the open angles in the contour of a model at a scale, the information of the distance and relative location between the two adjacent dominant points are suitably integrated as a set of features for describing a model, the features are invariant under rotation, uniform scaling, and translation of the curve.

该文提出了一种新的识别有遮挡目标的方法，即将目标模型和含有目标的遮挡图象的轮廓在某一尺度上张角的极值、极值点之间距离、相对位置等信息集成在一起，作为描述目标模型的一组特征，且这组特征在平移、旋转和均匀尺度变换下保持不变。

The basic idea is calculating wavelet coefficients for each time series based on Haar wavelet transform. The first k coefficients are used to form a MBR. Thus, the point filtering method can be used. In addition, lower bounding and upper bounding features of each time series are calculated in advance, which are stored into index structure. Finally, triangle inequality pruning method is adopted by calculating the distance between time series beforehand.

基本的思想为首先运用Haar小波变换计算每个时序的小波系数，利用前面的k个小波系数形成一个最小边界矩阵，以利用点过滤方法；然后将预先计算每个时序的低边界特征和上边界特征存放到索引当中；最后采用三角不等式来修剪不相似的序列并确保没有漏报。

In this strategy, the same image is code d by two different rules, then the pixels' position of image is changed by a transform between two different pixel address code spaces.

对于同一幅图像，采用两种不同的编码规则进行像素地址编码，然后借助这两个不同的点地址编码方式实现图像信息的置乱，该方法只需一次变换就能达到很好的置乱效果，具有一定的实践应用价值。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
