实现单纯形法求解最优化问题的步骤，两步法实现，可自由输入参数(Simplex method to achieve optimization step, two-step implementation of free input parameters)

image watermarking method

该算法是通过计算图像功率谱大小来评价图像的清晰度。清晰的图像功率谱大于模糊图像的功率谱。(The algorithm is derived by calculating the size of the image power spectrum to evaluate the clarity of the image. Clear image power spectrum is greater than the power spectrum of blurred image.)

The 2D RLS algorithms is used to enhanced image contrast by adaptive filtering techniques by less error and better speed recursively.

DTW（Dynamic Time Warping，动态时间归整）算法，该算法基于动态规划（DP）的思想，解决了发音长短不一的模板匹配问题，是语音识别中出现较早、较为经典的一种算法。用于孤立词识别，DTW算法与HMM算法在训练阶段需要提供大量的语音数据，通过反复计算才能得到模型参数，而DTW算法的训练中几乎不需要额外的计算。所以在孤立词语音识别中，DTW算法仍然得到广泛的应用。 (DTW (Dynamic Time Warping, dynamic time warping) algorithm based on dynamic programming (DP) ideas, sounds of varying lengths to solve the template matching problem, is speech recognition appeared earlier, more classic kind of algorithm. For isolated word recognition, DTW algorithm and HMM algorithm in the training phase need to provide a large number of voice data, obtained by repeated calculations to model parameters, while the DTW algorithm is almost no additional training calculations. Therefore, in isolated word speech recognition, DTW algorithm is still widely used.)

这是单自由度的非线性微分方程的求解程序（分段函数），可以画出动响应图和相图。(Nonlinear differential equation)
