利用RANSAC算法鲁棒性的计算两幅视图间的基本矩阵，本代码含有7点算法，8点算法(RANSAC algorithm using the calculation of robust fundamental matrix between two views, this code contains the algorithm 7, 8-point algorithm)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)

计算信号的模糊熵，其中的输入为一维离散时间序列(Calculate the fuzzy entropy of the signal, in which the input is one-dimensional discrete time series)

触发器，eda.在实际的数字系统中往往包含大量的存储单元，而且经常要求他们在同一时刻同步动作，为达到这个目的，在每个存储单元电路上引入一个时钟脉冲（CLK）作为控制信号，只有当CLK到来时电路才被“触发”而动作，并根据输入信号改变输出状态。把这种在时钟信号触发时才能动作的存储单元电路称为触发器(Triggers, eda. The actual digital systems often contain a large number of memory cells, and at the same time they often require synchronized action, to achieve this purpose, the introduction of a clock pulse (CLK) in each memory cell circuit as a control signal , the arrival of the circuit only when CLK was only trigger the operation and change the output state of the input signal. The memory cell circuit that can trigger actions when the clock signal is called a flip-flop)
