 average chain code 平均链码(6)
 平均链码
 CURVATURE CUTTING METHOD BASED ON AVERAGE CHAIN CODE 基于平均链码的曲率分割法 短句来源 (4) It studies the chain code and average chain code, bring forward a method of using the chain code difference to search for the turning points, then subjunctive beeline and change-length subjunctive beeline are used to distinguish linetype, and presents a practical algorithm. (4)研究了8-链码和平均链码,提出了用“链差”测定转折点,并用“虚拟直线”和“变长度虚拟直线”判断线型的方法,并给出了可实现的计算方法。 短句来源 This paper gives new definitions of line and average chain code, outlines the relation of average chain code and straight line chain code, and proposes the mechanism of line detecting and line contour tracking method. 在工程图纸矢量化中引入了平均链码和线条的概念，阐述了平均链码与直线链码的关系，提出了确定线条边界的切向和法向、线条检测、线条两侧同步跟踪以及转折处理的方法。 短句来源 The paper introduces concept of average chain code in cell image cutting,outline the relation of average chain code and curvature. Average chain code can be used to indicate angle of straight line and the curvature of curve,determine the curve break,realizing the automatic cutting of the cell image. 本文在细胞分割图象中引入了平均链码的概念 ,提出了平均链码与曲率的关系 ,平均链码可以表征直线的角度和一般曲线的曲率 ,从而确定折点的位置 ,实现细胞图象的自动分割。 短句来源 By the introduction of the concepts of relative chain code and absolute chain code, we proposed a simple and direct algorithm to compute chain code sum(average chain code). We found that tangent direction(slope) of edge point can be figured by the absolute chain code sum of three sequential points and curvature of edge can be figured by the difference of chain code sum between the three sequential points ingoing and outgoing. 通过引入相对链码与绝对链码概念得到了计算链码和 (平均链码 )的简捷算法 ,边界上连续 3点的绝对链码之和可以表示边界点的切线方向 (斜率 ) ,进入和离开边界点的 3点链码和之差可以表示边界的曲率 . 短句来源 更多

 The paper proposes a quick thinning and segmentation algorithm for hand-printed Chinese characters going on simultaneously. The memory space occupied by the character image data is only one four hundredth of that by the normal character matrix. Any hand-printed Chinese characer can be thinned and segmented into several simple lines,are and corner strokes. It is very efficient for structual feature extraction for Chinese characters. A new chain code for edge description is also proposed, whose average chain...
