汉字笔迹鉴别预处理的算法研究

手写体笔迹鉴别是计算机视觉和模式识别领域中的一个非常活跃的研究课题,是一种有效的身份鉴别手段。本文主要对笔迹鉴别的预处理进行了深入的研究。在预处理中的二值化时采用通过迭代能自动确定阈值的算法,明显提高了对笔迹图像特征信息的保留。去除噪声采用改进的中值滤波,能自动确定去噪门限,使得对一些零散的噪声去除效果明显提高。在MATLAB 7.0平台上经过多次反复试验证明了本文所使用的预处理系统快速稳健。

Algorithms of the Preprocess Research on Chinese Handwriting Identification

Handwritten handwriting identification is one of the most important branches of computer vision and pattern recognition,and an effective means of identification.A deep research on pre-processing of Chinese handwriting identification was conducted in this paper,and computer can automatically found the threshold through the use of an iteration algorithm in binarization,as it can retain more Texture features of image.In denoising,we also used a improved median filter to automatically determine the noise thresh...
