The baseline direction that verifies the page skew can be calculated according to the eigen-points in a text line. 它将字符连通区包围盒底边中心点作为特征点,利用文本行中特征点与基线的关系,计算出基线的方向,即为页面倾斜方向。
Three approaches to the graphic representation for lines of intersection are introduced in this article, namely, central projection, parallel skew projection and arc line projection. 本文介绍了图解截交线的三种方法,中心投射法、平行斜投射法、弧线投射法。
Construction technique of jack-in between junctions of skew frame for existing railway line 既有线斜交框架中继间顶进施工技术
Rolling process in high-speed wire line can be conducted successfully without skew and twist if the line can be regulated automatically. 在高速线材轧制过程中,轧件发生偏斜和扭转如果能够实现自动找正,则可保证顺利轧制。
The paper makes hydro-technological model test for a certain skew transporter bridge with multi line large angle, to counter the condition of multi-line skew transporter bridge with larger skew angle and the characteristics now of calculation method that is lack of theory and experience. 该文针对多线斜交桥渡在斜交角度较大的情况下,目前尚缺少理论及经验计算方法的特点,对某多线大角度斜交桥渡进行了水工模型试验。
After skew correction, Hough transform is used to construct the structured elements, which in turn are applied to the hit or miss operator for mathematical morphology-based line extraction ( MMLE). 然后根据这些结构元素,利用数学形态学中的击中/击不中变换提取文档图像中的直线(MMLE)
As for skew correction, this paper introduces a new form-line detection method based on directional projection. A System of Table Line Processing that Base on the One& way and Quasi Connection 对于图像的倾斜校正,我们提出了基于方向投影的表格线检测方法,并由此实现图像的自动分类;单向准连通的表格线检测算法
According to the feature that the Stored-Grain Insects images haven't the obvious lines, a new skew detection method based on directional projection is presented, using Bresenham's integer only line drawing algorithm. 针对无明显的直线特征的仓储害虫图像,提出了一种基于整数Bresenham算法求方向投影值,利用方向投影值检测图像的倾斜角度的方法。
According to the property that most bill images have the form lines, a new skew detection method based on directional projection was presented, using Bresenham's integer only line drawing algorithm. Then, the new method was compared with the Hough transform method. 针对含有表格线的票据图像,提出一种基于整数Bresenham算法求方向投影的倾斜检测方法,并与Hough变换方法进行了比较。
In recent years, with the limitation of environmental conditions, the skew crossing, the curve bridge, and complex loading of the bridge are usually adopted in urban bridge construction, while in high-level line, the skew and the curve bridge are also common. 近年来,在城市桥梁建设中,由于周围环境条件的限制,往往要采用斜交桥、曲线桥等受力复杂的桥梁。
The experiments are performed on the image database containing ten scripts with different skew angles. The results confirm that the algorithm can identify scripts accurately and is robust to the skew of text line at the same time. 4. 对十种文字的文本图像进行不同倾斜角度的文种识别实验,结果表明该算法具有较高的识别率且对文字行倾斜具有较强的鲁棒性。
Yet, irregular layout and asymmetric bearing characteristics of skew girder bridges cause special and complex seismic response and skew bridge is destroyed more serious than straight line orthogonal bridge under earthquake. 但是这种不规则的平面布置和非对称的支承特性造成了斜交桥特殊和复杂的地震反应,斜交桥遭到地震破坏也比直线正交桥梁更加严重。
