In a small local neighborhood, the ridges and furrows approximately form a two dimensional sinusoidal wave along the direction orthogonal to local ridge orientation. Thus, the ridges and furrows in a small local neighborhood have well defined local frequency and ....

....graylevel fingerprint images [2, 15, 8, 18, 19] However, they usually assume that the local ridge orientations can be reliably estimated. In practice, this assumption is not valid for fingerprint images of poor quality, which greatly restricts the applicability of these techniques. Hong etal: [4] proposed a decomposition method to estimate the orientation field from a set of filtered images obtained by applying a bank of Gabor filters on the input fingerprint images. Although this algorithm can obtain a reliable orientation estimate even for corrupted images, it is computationally ....
