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 提出一種多方向手寫筆跡文本行的提取方法.該方法以視覺感知理論為基礎(chǔ),采取自底向上的策略,先將筆畫組合成類比字符的筆畫塊,然后基于這些筆畫塊建立鏈接模型,最后采用分支限界搜索算法從鏈接模型中找出最優(yōu)行排列.實驗結(jié)果表明,該方法能有效地提取多方向筆跡行結(jié)構(gòu),并適用于彎曲文本行的提取
