摘要
字线交叠严重干扰对字符的切分与识别。基于二值图像的表格框线去除算法,只能在一定程度上排除表格框线对字符识别的干扰。随着计算机运算速度和存储容量的迅速提高,表格识别系统的扫描输入图像开始采用灰度图像和彩色图像。该文提出了一种基于彩色图像的表格框线去除算法,由于利用了图像中的彩色和灰度信息,能更好地排除表格框线对字符识别的干扰。该方法目前已成功地应用于银行票据识别系统中。
Characters often overlap form frame lines. Such overlapping seriously deteriorates the recognition of characters. Almost all form frame line removal algorithms based on binary image, and these algorithms have some limitations. A new form frame line removal algorithm based on color images is presented in this paper. Because of using color and gray information of images, this method can avoid the effect of overlapping better. The effectiveness of this method is proved by application of financial document recognition system.
