抽取曲线

This paper presents an approach to perceptually extract multi - oriented text lines from online handwriting . the approach adopts a bottom - up strategy . by the approach , strokes are first merged into blocks analogous to words , then a link model is constructed upon these blocks . finally , the optimal text line layout is found out by a branch - bound search on the link model . the experimental results show that the approach is effective and also available to extract curved text lines
提出一种多方向手写笔迹文本行的提取方法.该方法以视觉感知理论为基础,采取自底向上的策略,先将笔画组合成类比字符的笔画块,然后基于这些笔画块建立链接模型,最后采用分支限界搜索算法从链接模型中找出最优行排列.实验结果表明,该方法能有效地提取多方向笔迹行结构,并适用于弯曲文本行的提取
