Image Enhancement of Fingerprint Scanners Based on P-M Equations
摘要
Abstract
There are mosaics, noise, fuzziness in the images of fingerprint scanner with cheap SMOS chips. For im⁃proving the image quality, this paper presents a synthesis method combining USM with PM equations, which effec⁃tively sharpens the edge and reduces the noise of the images. The experimental results prove that the images pro⁃cessed can be up to international certification standard.关键词
