Abstract

One of the common techniques of printing gray scale images using a bi-level device such as a commercial laser printer is Error Diffusion. Since most of the fingerprint images are gray scale images, they too can be printed using error diffusion. However, none of the existing popular error diffusion algorithms makes use of the ridge-flow information present in a fingerprint image. In this note, we explore the use of ridge-flow directions in a fingerprint image for the purpose of the error diffusion in printing fingerprint images.
