摘　　要：针对现有文本定位方法仅面向水平方向文本的问题,提出了一种基于形态学的多方向文本定位方法。首先利用边缘提取和梯度特征对文本进行粗检测,形成候选文本区域;然后通过形态学骨架化操作得到连通域骨架并对骨架进行分割;最后通过连通域分析滤除虚检的候选文本区,得到精确的检测结果。实验结果表明,提出的方法能有效处理水平和非水平方向的文本。To solve the problems that existent methods detect horizontal text, multi-oriented text location method based on mathematical morphology was raised. Edge extraction and gradient feature were exploited to coarsely detect and obtain candidate text regions. And then text connected components were obtainted by Mathematical Morphology skeletonization and were segmented. Finally the false detected candidate text regions were filtered by connected-component analysis to obtain the fine detection results. Experimental results have shown that the proposed approach can handle effectively horizontal and non-horizontal text.
