I have uploaded a code for DCT watermarking..I have embed a basic matrix into original image and calculated the difference.

今日对光谱数据预处理中的MSC（多元散射校正）和SG（0阶、高阶）平滑进行了学习，参考书目是李志刚老师著的《光谱数据处理与定量分析技术》（原理介绍较为详细）并结合CSDN和联合开发网上下载的代码进行了简单的matlab编程。代码稍后上传，介绍详细，感兴趣的可以去看看。(Today, MSC (Multiple Scattering Correction) and SG (0th order, high order) smoothing in spectral data preprocessing are studied. The bibliography is "Spectrum Data Processing and Quantitative Analysis Technology" by Li Zhigang (more on the principle) . And combined with CSDN and joint development of the code downloaded online to carry out a simple matlab programming. The code is uploaded , and the details are detailed. If you are interested, you can check it out.)

计算信号的短时傅里叶变换，对信号进行时频分析(Calculate signal short-time Fourier transform, the signal time-frequency analysis )

有循环检测，周期性检测，时间序列数据分析中的梅林变换工具，最大信噪比的独立分量分析算法。( There are cycle detection, periodic testing, Time series data analysis Mellin transform tool, SNR largest independent component analysis algorithm.)

求复杂图形的等值线平面图，能够均匀地画出三维图形的等值线图(Find the contour plan of complex graphics, can be evenly draw the contour map of three-dimensional graphics)

Optimal Production Planning Formulation

说明：  A new technique of free-space simulation has been developed for solving unbounded electromagnetic problems with the finite-difference time-domain method.
