论文摘要
讨论了不同类的螺纹指纹。使用微分方程创建具有参数theta的一般动力学系统,通过改变theta的值来模拟这些类。研究了全局动力学,并分析了平衡的存在和稳定性。枫木用于可视化指纹方向图像,作为平面动力学系统相位肖像的平滑变形。
Different classes of the whorl fingerprint are discussed. A general dynamical system with a parameter theta is created using differential equations to simulate these classes by varying the value of theta. The global dynamics is studied, and the existence and stability of equilibria are analyzed. The Maple is used to visualize fingerprint orientation image as a smooth deformation of the phase portrait of a planar dynamical system.
