说明：  我提供了一个基于FXLMS的单通道前馈有源噪声控制系统的一个小例子. 为了减少噪声，我们使用控制器C（z）产生另一个“噪声”yw（k）。我们希望它破坏性地干扰X（k）。这意味着控制器必须是传播介质P（z）的模型。采用最小均方算法对控制器系数/权重进行调整。 然而，还有流体介质S（Z）留在致动器和传感器之间。我们称之为二次传播路径。所以，为了使解正确，我们需要用SH（z）来补偿调整过程，这是S（z）的估计(I provided him a little example of a single channel feed-forward active noise control system based on the FxLMS. To reduce noise, we generate another 'noise' yw(k) using the controller C(z). We hope that it destructively interferes x(k). It means that the controller has to be a model of the propagation medium P(z). Least mean square algorithm is applied to adjust the controller coefficient/weight. However, there is also fluid medium S(z) that stay between the actuator and sensor. We called it the secondary propagation path. So, to make the solusion right, we need to compensate the adjustment process using Sh(z), which is an estimate of S(z).)

斯坦福开发的Jetsurf2.0 动力学模型，可用作大分子，航空燃料的燃烧仿真计算。适合在chemkin上运行。(JetSurF2.0 consists of 348 species and 2163 reactions. The development effort centers on n-dodecane and n-butyl-cyclohexane, but the model includes also the high-temperature chemistry of all n-alkanes up to n-dodecane, and mono-alkylated cyclohexanes, including n-propylcyclohexane, ethylcyclohexane, methylcyclohexane and cyclohexane)

实现二值化，当像素值（r+g+b）/3>128时设为255,当像素值小于128时设置为0.做归一化处理后，2值化的颜色 1为白，0为黑。边缘部分，计算有误差，255,254,253,252 就算白，0，1，2，3，4就算黑。屏幕显示时，肉眼是分辨不出这点误差的。你可以对2值化后的图像值作归一化处理，得到1和0，然后再放大（乘255），就可得到满意的数值。至于左边界上 1 254 253， 0 255 255，可能是2值化前，颜色原本就有差别。不是2值化的错误。
