几种脱机手写女书特征提取法的比较研究

摘要

目前,OCR 技术已取得了多项研究成果.但是几乎没有人从事女书文字识别的研究.女书的特征提取是女书文字识别中的一个重点和难点.文章通过比较几种特征提取算法,提出一种基于 G-DCD 改进的特征提取算法,并用该算法正确提取手写体女书文字特征.%Currently, OCR technology has made a number of research results, but almost no one in nu shu character recognition. The feature extraction is important and difficult in nu shu recognition. Through comparing of several feature extraction algorithm, the article introduced the improved G-DCD feature extraction algorithm, which correctly extracted handwritten nu shu feature.
