本文提出了一种有限样本集上基于次特征值误差补偿和优势主向量上非对称分布的马氏距离
改进算法. 通过改进的马氏距离, 有限样本导致的次特征值误差得到补偿, 样本特征矢量在变换 …

This paper presents a dynamic approach to document page segmentation based on inter-
component relationships, local patterns and context features. State-of-the art page …

This paper presents several directional features with different meshing methods for
Handwritten Chinese Character Recognition (HCCR). Local elastic meshing technology is …

纸币分类技术, 通过对每个币种预先定义规则来实现. 这种方法的不足之处在于增加新币种的
时候, 必须增加与其对应的规则. 一种更为有效的方法就是对纸币图像的特性进行分析 …

A comprehensive literature review is conducted on the considerations of the human finger
and Chinese character in finger interaction for Chinese input. The results of this study …

Feature extraction is a very important step in the process of character recognition. The
features extracted from the character should encode the local, global and the structural …

In this chapter, we describe an adaptive Indic OCR system implemented as part of a rapidly
retargetable language tool effort and extend work found in [20, 2]. The system includes script …

提出了一种基于笔划的手写体汉字方向分解特征提取的新方法. 根据每个笔划像素点及其邻域
像素点的方向分布特征, 汉字图像被分解为“横”,“竖”,“撇” 和“捺” 4 种子模式 …

The journey of research for Document Analysis and Recognition (DAR) started with the
problem of automatic character recognition. Today, it has covered a vast span of recognition …

本文在基于动态网格的手写汉字特征抽取方法中引入重叠网格划分, 定义了一种反映书写结构的
加权点密度, 并提出了一种根据密度投影计算模糊隶属度的方法, 这些措施提高了特征的分类 …
