Abstract: 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.
