| Abstract: | A combinatorial algorithm based on the directional segmentation is proposed for the pre processing of the fingerprint images, which can improve the accuracy and reliability of the automatic recognition of fingerprint images. This combinatorial algorithm is composed of directional image computation, smoothing, directional filtering, local self adaptive binarization, noise elimination and thinning. Such an algorithm can enhance the fingerprint images and reduce the effect of the rotation and shift of the images on the fingerprint recognition. |
