用VC实现的指纹识别系统，功能完备。To match a Fingerprint image with a one already stored in the database. A fingerprint image essentially consists of a set of minutiae on the plane. Minutiae are the terminations and bifurcations of ridge lines in a fingerprint imag
指纹检测识别matlabIn this paper the problem of fingerprint verification via the Internet is investigated. Specifically, the method that is used for the above purpose is based on a traditional finger scanning technique, involving the analysis of small uniq
This paper proposes a Filippov epidemic model with piecewise continuous function to represent the enhanced vaccination strategy being triggered once the proportion of the susceptible individuals exceeds a threshold level. The sliding bifurcation and
A two-degree-of-freedom system with one-side amplitude constraint subjected to periodic excitation is considered. Dynamics of the system are studied with special attention to Hopf bifurcations of period motions in two kinds of strong resonance cases
We consider the van der Pol equation with discrete and distributed delays. Linear stability of this equation is investigated by analyzing the transcendental characteristic equation of its linearized equation. It is found that this equation undergoes
We show that dielectric waveguides formed by materials with strong optical anisotropy support electromagnetic waves that combine the properties of propagating and evanescent fields. These “ghost waves” are created in tangent bifurcations that “annihi
