摘　　要：探讨了一种印刷体数字符号快速识别算法, 采用图像旋转、去噪声、图像分割等手段对含有印刷体数字符号的图像进行预处理, 然后根据印刷体数字的字符结构提取 4种稳定且有效的结构特征, 即横线特征、竖线特征、水平方向过线数和垂直方向过线数. 根据这些特征构造编码器, 进行编码识别, 使用VC++编程实现. 实验表明, 该算法速度快、精度高, 有一定的抗干扰性.A fast recognition algorithm for printed numeric symbol is introduced.The pre-process to the image with printed numeric symbol is carried out.To be exact,image rotation, anti-noise and image segmentation are used,which is very important to the follow-up recognition effect directly.There are four kinds of steady and effective structure features according to the structure of printed numeric symbol:horizontal line feature , vertical line feature, horizontal through-line number and vertical through-line number.Then the encoder is constructed,recognized and programed with VC++. Thus, a fast and precious algorithm with certain anti-interference can be achieved in experiment.
