    • Disclosed is a method of sequencing character information in order to increase precision of character recognition. The method includes: a pre-processing that extracts character information from an image to binarize the extracted character information through a predetermined threshold and extracts and thins a center line of the binarized character information; normalizing the pre-processed character information to character information according to a predetermined criteria; and sequencing the normalized character information using structural features including an end point or a divergence point of the character information. The present invention suggests an angle normalization method of input character information, a structural feature position determining method, and a structural feature numeral string generating method to strongly recognize characters configured by various fonts obtained from a natural scene regardless of an angle or a size of the characters.
    • 公开了一种对字符信息进行排序以提高字符识别精度的方法。 该方法包括:预处理,其从图像提取字符信息,以将所提取的字符信息二值化为预定阈值,并提取并清除二值化字符信息的中心线; 根据预定标准将预处理字符信息规范化为字符信息; 以及使用包括字符信息的终点或发散点的结构特征对归一化字符信息进行排序。 本发明提出了一种输入字符信息的角度归一化方法,结构特征位置确定方法和结构特征数字串生成方法,用于强烈地识别从自然场景获得的各种字体配置的字符,而不管角度或尺寸如何 人物。
