(From Hong, L., Automatic Personal Identification Using Fingerprints, Ph.D. thesis, 1998.) One typical variation of this theme segments the image into non-overlapping square blocks of width larger than the average inter-ridge distance. Using a bank of directional bandpass filters, each filter generating a strong response indicates the dominant direction of the ridge flow in the finger in the given block. The resulting orientation information is more accurate, leading to more reliable features. A single block direction can never truly represent the directions of all the ridges in the block and may consequently introduce filter artifacts. One common directional filter used for fingerprint enhancement is the Gabor filter. 60 Gabor filters (see Figure 8.17) have both frequency-selective and orientation-selective properties. For example, a properly tuned Gabor filter will pass only fingerprint ridges of certain spatial frequency flowing in a certain specific direction. Typically, in a 500 dpi, 512 × 512 fingerprint image, a Gabor filter with u 0 = 60 cycles per image width (height), the radial bandwidth of 2.5 octaves, and orientation θ models the fingerprint ridges flowing in the direction θ + π/2. -200 -200 -100 -100 0 0 100 100 200 200

Jain, A.K. and Pankanti, S., Handbook for Image and Video Processing, Bovik, A., Ed., ©Academic Press, April 2000.) A novel approach to fingerprint enhancement proposed by Hong et al. 10 (see Figure 8.18) is summarized here. It decomposes the given fingerprint image into several component images using a bank of directional Gabor
