利用固定区域坐标提取固定区域的单行数据字符块；基于高斯模糊提取随机手写黑子信息字符区；结合 Hough 变换与投影技术完成随机手写区域中包含多个黑子记录字符块的分割，并将包含单个黑子记录字符块分割为3个仅包含单行数据的字符块；利用颜色填充分割算法分割出单行数据字符块中的单个字符和粘连字符，结合平均字符宽度信息进一步分割粘连字符。实验结果表明，每幅手绘太阳黑子图的固定区域和随机区域的字符分割平均正确率分别达到95.5%和79.6%。

Using fixed region coordinates to obtain a single row character data block of fixed region. Based on Gaussian blur to extract handwritten sunspot random region. Using projection and Hough transform to complete segmentation of character block included some sunspot records and divide single sunspot records character block into three character blocks which contains only a single row data. Using color filling segmentation algorithm to split a single character or adhesion character from a single row character data block, and implement further segmentation of adhesion characters based on average character width. Experimental results show that character segmentation correct rate of fixed region and random region reached separately an average of 95.5%and 79.6%.
