基于进化规划算法的医学图像描述 分割函数是最大熵双阈值函数(the segmentation of image)

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

锁相环就是锁定相位的环路。学过自动控制原理的人都知道，这是一种典型的反馈控制电路，利用外部输入的参考信号控制环路内部振荡信号的频率和相位，实现输出信号频率对输入信号频率的自动跟踪，一般用于闭环跟踪电路。(Locked loop (phase), as the name implies, is the lock phase of the loop. Principle of automatic control of the people know, this is a typical feedback control circuit, the external input reference signal control the frequency and the phase of the oscillation signal inside the loop, the frequency of the output signal of the input signal frequency automatic tracking, generally used for closed-loop tracking circuit. )

This function returns the numerical derivative of an analytic function. Of special note, is the incorporation of the "complex stepderivative"approach which offers greatly improved derivative accuracy compared to approximations. This is especially germain when accuracy at the level of machine precision is a concern. (Programming the finite element toolbox using matlb finite element toolbox, many examples for yourself as there is a very friendly interface, input parameters can be)
