- W2347698712 abstract "A fingerprint enhancement algorithm based on wavelet transform and filter in frequency domain is put forward in this pa-per. At first a fingerprint threshold segmentation algorithm based on wavelet transform is brought out which separates the foreground and background of the fingerprint image effectively. Wavelet transform is done in the frontground. Only the low-frequency part is used to determine the ridge orientation and frequency information, so that the effect of the high-frequency information as noise could be restrained. Aiming at the different characteristics and enhancement goals between the low-frequency part and the high-frequency parts, Gabor filter is designed in the low-frequency part while orientation filter is designed in the high-frequency parts. At last reconstitute the image. The experimental result shows that this approach can enhance fingerprint image quality effectively." @default.
