摘要：

A nonlinear orientation model for the representation of the orientation matrix of a fingerprint image is presented. A general procedure to obtain the set of parameters describing this model is shown. Particularly, a piecewise linear orientation function is analysed. The model, compared with a previous zero-pole model, shows substantial decrease in the orientation error. The application of this model for efficient identity verification based on the ridge orientation is explored. Copyright (C) 1996 Pattern Recognition Society.
