中文摘要:
      针对传统汉字切分方法中对粘连汉字和重叠汉字切分不准确的问题,提出了基于极小阈值和曲线拟合的垂直投影汉字切分算法.该算法在传统垂直投影法汉字切分的基础上结合极小阈值和曲线拟合进行切分,实验结果表明:相对于传统汉字切分方法,该算法对含有粘连和重叠现象的手写体汉字文本的切分是有效的,从而可使手写体汉字的切分准确率有较大的提高.
英文摘要:
      Aiming to solve the disadvantages of traditional handwritten Chinese character segmentation method, especially for segmentation inaccurate problem of adhesion characters and overlap characters, this paper presents an algorithm of vertical projection characters segmentation based on minimum threshold and curve-fitting. This algorithm combines minimum threshold and curve-fitting with traditional segmentation method. Experimental results show that this algorithm is effective for adhesion characters and overlap characters, and it can improve segmentation accuracy of Chinese characters.
