Daugman虹膜识别方法的研究,利用2_D Gabor filter进行Iris Recognition. MATLAB实现基于Daugman的虹膜提取算法源代码Iris-Segmentation(Daugman iris recognition method, using 2_D Gabor filter for Iris Recognition.MATLAB based on Daugman)

实验要求：在一张图上绘制三种二进制信号（即反极性信号、开关信号和正交信号）的误码率。这三种信号可以在几何上用“信号空间”中的点来表示。在反极性信号情况下，信号是±s(t)，每个都有能量E。开关信号也是一维信号，所以两个信号为0和s(t)，正交信号我们上课已讲过。要求信噪比为0：12dB。(Experimental requirements: to draw a diagram of three binary signals (i.e., reverse polarity signal, the switching signal and quadrature signal) BER. These three signals can be in the geometric point in the signal space. In the reverse polarity signal case, the signal is s (t), each have energy E. The switching signal is also a one-dimensional signal, so the two signals is 0 and s (t), the quadrature signals teach us have talked. Signal-to-noise ratio to 0:12 dB.)

不平衡电网条件下，逆变器根据并网准则的要求，需要不脱网运行，并提供无功支撑。本仿真实现了不平衡条件下的逆变器低穿运行，并实现在故障后快速的功率回复(Under unbalanced grid conditions, the inverter according to the guidelines and requirements of the network, you need not run off the network, and provide reactive support. The Simulation of the inverter under unbalanced conditions, low wear operation, and after the failure to quickly realize the power of reply)
