Modeling orientation fields of fingerprints with rational complex functions
Pattern Recognition(2004)
摘要
In this paper, a novel model is proposed for the orientation field of fingerprints, which can be expressed as the argument of a rational complex function. It is suitable for all types of fingerprints. Experimental results show that it performs much better than the previous works.
