匹配

At every step only one subpattern is used to perform pattern matching, and a part of reference patterns which have less distances to the unknown pattern are retained to match further in the next step.

这样使匹配过程加快三倍以上。文中给出了在语言识别方面的实验结果。采用二种淘汰办法，它们在前三级上的淘汰率分别是：3/4，1/2，1/2；9/10，1/2，1/2。这二种办法所需的图样匹配时间分别是0.359T_0和0.294T_0，T_0——是完整的匹配过程所需的时间，而正确率几乎不下降。

When the cell searched a GPS Bluetooth device, it demands input the latter's password. The default password is 1234 and device name is GPS. Once the pair match is successfully completed, if the Bluetooth function on both GPS and cell-phone is turned-on, the navigator's Bluetooth will connect automatically.

匹配状态为被查找状态，需要用手机主动查找GPS蓝牙设备，手机查找到GPS设备后在手机方要求输入该设备密码，默认密码为：1234，经匹配连接后的设备无需每次匹配，只要GPS和手机的蓝牙功能打开，启用本机蓝牙功能便能自动连接上，同时在自动连接同时会出现如下界面，其中数字0表示连接时所用的时间。

In this algorithm, the strongest corner points is adaptively detected with Harris operator and (2n+1)×(2n+1) feature windows is selected for originally mutual gray correlative matching. Continental distance ratio invariant criterion is proposed, and consistency of motion vector is improved by eliminating error matching points with median filter. 9 pairs right points is preserved, 4 pairs composing 1 group, and 5 groups is random distributed to uncoil the motion vector equations. Last, stabilization precision is improved by averaging the 5 groups' solutions.

该方法用Harris算子自适应检测出最强壮的角点，开辟(2n+1)×(2n+1)特征窗进行灰度互相关初匹配；提出欧式距离之比不变准则，通过中值滤波剔除误匹配点，确保运动矢量较高的一致性；最后保留若干正确的匹配点对，分成多组解运动矢量方程，将多组解的平均值作为全局运动矢量以提高稳像精度。

But because of undistinguishable feature region or no feature region, the matching will be defeated. Then we design another method to find out the based point. It is taken as matching template.

一旦因为特征不明显而造成特征匹配失败，接着就进行基于点的匹配，通过采样到的基本点作为模板来完成图像间的匹配过程。

In order to reduce the cost of matching, we used multiple scale technique. 4. We presented a novel method of searching for similar fragments of 3D curves. with this method, a hash vector is associated with each fixed-length fragments of 3D sherd. Each vector consists of low frequence component of Fourier-Like spectrum for the distance between profile curve and the centroid.

依据样条曲线的基本理论，研究了基于B样条的轮廓曲线的匹配方法，给出了由轮廓曲线不变量曲率和挠率构造的相似不变量的选取以及基于相似矩阵的匹配算法，并对该算法的时间复杂度作了估计，同时，将多尺度技术引入到物体轮廓的匹配问题中。

Degree sum conditions of IM-extendable graphs are researched. The main results are as follows:(1) Let G be a graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,, then G is IM-extendable.(2) Let G be a claw-free graph with 2n vertices.

In the results of the fMRI experiment,the activation level of picture-word identical matches condition is less than that of the categorical matches and non-matches conditions in precuneus,frontal and occipital areas,which shows repetition inhibition phenomenon.

4fMRI实验结果中，图-词的名字匹配在楔前叶、额区和枕区的激活比不匹配和类别匹配少，表现出重复抑制。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
