传真图象缩放的快速操作

主要讨论一种改进了的图象缩放算法，针对二值图象的特殊性。采用生成固定的进取序列来代替重复繁杂的浮点运算，达到图象缩放的整数化实现。最后用Ｃ语言加以实现。

A Quick Algorithm of Resizing Fax Image

Fax image is one kind of two-value image. This paper focuses on the design ofan improved algorithm which can quicken traditional resizing operation on two-value image. Aiming atthe speciality ofthe two-value image, the improved algorithm substitutes the repetitive and complex floating-point operation with generatinga fixed pick-up, sequence. It only nceds integer operation in image resizing. At last. we implement it with C language.
