Abstract

The effect of image enhancement has an impact on features extraction and the fingerprint identification of recognition rate, according to the research of traditional fingerprint image enhancement technology, an improved Gabor filtering for fingerprint image enhancement technology is proposed, using orientation selection and frequency selection characteristics of Gabor filtering, local orientation of fingerprint image and ridge line frequency are the parameter of Gabor filtering function, the two-dimensional Gabor filter is divided into a one-dimensional band-pass filtering and a one-dimensional low-pass filtering. The algorithm has increased computing speed and efficiency and has a good robustness.
