图像文本识别中目标定位方法研究

目标定位是图像文本识别的关键步骤。为了增加检测的可靠性,依据文本区域存在丰富的一致性边缘这一特性,改进了传统的基于Sobel边缘检测与形态学运算结合的文本检测方法,在此基础上采取了轮廓跟踪以及与先验知识结合的算法而实现了精确定位。

Research on Target Location Method in Image Text Recognition

Targeting is the key step for image text recognition.In order to increase the reliability of detection,according to the fea-ture of text area has rich consistency edge in this article,improve the traditional text detection methods which is combined edge de-tection based on Sobel with morphological operations,on this basis adopted the algorithm of contour tracking and combination with priori knowledge to achieve accurate positioning.
