Branch system is simply designed too . at last , point symbol achieved has tested with image match . lt will improve a reference for topographic map pattern automatic recognization , it has significance of theory and practice 并通过影像匹配法对地形图符号获取进行了初步实验。为进一步实现地形图模式识别自动化开发提供参考,具有一定的理论意义和实用价值。
In local vector match method , we add the line numbers and the dispersion of direction angle between the center point and near minutiae point . we also add the direction angle of the center point . these additions enhance veracity of the minutiae feature matching 在局部向量特征匹配法中加入了中心点与邻近特征点的纹线数,方向角差,中心点的方向角等特征信息,提高了特征匹配的准确性。
And it firstly analyzes some character recognition algorithms used much at present , such as template matching algorithm , characters features algorithm and artificial neural network algorithm . and then it puts forward thoughtway of combination of character recognition algorithm 同样,先对目前常用的字符识别算法(模板匹配法、字符特征法、人工神经网络)进行分析,然后提出组合识别法字符识别思想。
The analysis method adapted in this paper is the conservation of complex power technique combining even and odd mode analysis method , more accurate results have been obtained when correction to the errors due to electrical wall condition in the section of the metal septum is introduced 在分析方法上,本文采用复功率守恒技术和奇偶模分析法,并考虑到膜片端面电壁条件的修正,因而比一般的模匹配法有较高的精度。
As the most direct and simplest motion estimation algorithm , full search has much high computation complexity and is difficult to be integrated into real time video encoding systems . many fast block matching methods have been proposed to decrease computation load 全搜索快匹配法是最简单最直接的块匹配运动估计法,但是由于其运算复杂度太高很难应用于实时视频编码中,从而业界提出了很多种快速块匹配运动估计方法。
If the match succeeds , the recognition result will be attained directly , otherwise the characteristic district pattern match will be applied to the similar characters and the hollow template pattern match will be applied to other conditions 该方法定义前景匹配度、背景匹配度和整体失配度3种匹配测度进行模板匹配,匹配成功则直接获得识别结果,否则,对相似字符情形应用特征区域模板匹配法,对其他情形应用空心模板匹配法。
3 、 chinese words divided syncopation technology is the difficulty of the query technique based on phrase . some divided syncopation such as mechanical matching method , feature phrase library method , restriction matrix method , syntax analysis method and comprehended syncopation method are emphasized 对其中的几种方法,如机械匹配法(即mm法) 、特征词库法、约束矩阵法、语法分析法和理解切分法等做了详细的比较和分析,并归纳出各自特点。
Studied on floating avoiding method and the memory conflict regulating method to realize the real - time image capture . 2 . using four subpixel - locating methods to obtain the center of micro parts , which are template - matching method , core - shape method , centrobaric gray method , and edge - fitting method 利用模板匹配法、型心法、灰度重心法和边缘拟合法等四种亚像素定位方法实现了对零件中心位置的检测;利用图像旋转方法,进行了零件旋转角度定位研究。
The system adds the image recognition function on warning signal lights except the traditional video monitoring , remote control and collecting alert signals function etc . the methods for alert signal recognition include gray histogram arithmetic , pattern matching method and hsi system . the gray histogram arithmetic is the best method for this system 除了实现传统视频监控系统所具有的监视、远程控制、告警信号采集等功能外,增加了基于颜色特征的告警信号灯图像识别功能。确定了三种可用于基于颜色特征的告警信号灯识别的方法:灰度直方图法,模板匹配法和hsi系统法。
The edge of a group of blood is visible and easy to track . there is little distortion of the shape of a group of blood between two frames . there are many methods to measure blood velocity such as optical flow techniques [ 40 , 44 , 45 ] , using fluorescent images [ 42 ] , template matching method [ 17 ] and so on [ 43 ] 大血管的情况复杂一些,第一类血管的血液和周围的组织都很复杂(见图3 . 1 ) ,这类血管有些血液和组织还很相似,特征是流速比较低,细胞团块边缘清晰,在一定时间内的形变较小,本文用模板匹配法,较好的测量出这类血液的流速。
