摘要
本文给出了一种将２４×２４点阵汉字放大为４８×４８点阵汉字并平滑的方法．放大操作是对二值点阵按位进行运算，平滑操作不是对放大后的二值点阵按位操作，而是根据放大后图象的特性在需要平滑的地方进行操作，用该方法得到的汉字质量令人满意．
48×48 dot matrix cmnese character can be obtained from 24×24 dot matrir chinese character．The（0，1）lattices chinese character is obtained by two steps：the first，called simple magnifying operation is executed bit by bit；the second，called smoothing operation is executed only at the bits which need to be done in output image．These bits can be found out by analysing characters of the magnifying picture．The Quality of chinese characters obtained by the method is satisfactory．
