-A two-phase singularity detection. Fingerprint image block, calculate the direction of each block constitute a block pattern, and pattern in the block based on the use of the distribution of the direction of the neighborhood together with the improved Poincare Index method to determine the singular point where the candidate regions of the candidate region of pixels re-calculated to determine the rate of change of local direction of the precise location of singular points. This method is used to FVC2004 DB1_A fingerprint database of images, experiments show that this method of noise on the fingerprint image has good robustness and computing simple and fast, easy to implement.

Description: 研究了具有滞后非线性的汽车悬架在路面拟周期激励作用下发生受迫振动时的混沌运动。首先用melnikov方法给出了发生混沌运动的临界条件，然后研究了非线性阻尼力中的各系数对混沌的影响，最后通过Poincare截面及Li指数揭示出在此系统中存在着从拟周期运动通向混沌运动的可能性-Studied with a lag in road vehicle suspension nonlinear excitation of quasi-periodic forced vibration under the action of chaotic motion when. The first method used melnikov gives the critical condition for chaotic motion, and then study the nonlinear damping force of the impact of each factor on the chaos, and finally through the Poincare section and Li index reveals the existence of this system from the quasi-periodic motion leading to the possibility of chaotic motion
