DCT watermarking code for embedd and extract

支持向量机方法，用matlab实现，用于分类检测、模式识别，人脸检测等(matlab implementation for classification detection, pattern recognition, face detection, etc.)

说明：  基于matlab的MCMA算法仿真程序，给出均衡前后均衡效果图(Based on the MCMA algorithm matlab simulation program is given before and after the balance of the effect of a balanced graph)

A fixed-point series cascade form filter can be constructed using the fundamental building blocks of delay, sum, and gain.

说明：  通过设计模糊PID控制器，实现对直线、圆轨迹较为精准的跟踪(By designing a fuzzy PID controller, the accurate tracking of straight and circular trajectories can be achieved.)

不仅仅是闲了二进制二进制随机序列的频率调制，而且实现了其相应的解调过程，FSK完整程序(Not just free of the binary random sequence of binary frequency modulation, and the realization of the corresponding demodulation process, FSK complete procedures)

Convert color images between RGB, YCbCr, HSV, HSL, CIE Lab, CIE Luv, CIE Lch, and more.

Transmit without regrets Online optimization in MIMO-OFDM cognitive radio systems

说明：  基于matlab实现人工势场算法，同时改进算法约束条件，避免算法陷入极值局部小的可能(The artificial potential field algorithm is realized based on MATLAB, and the constraint conditions of the algorithm are improved to avoid the possibility of the algorithm falling into the local minimum of the extreme value)

it helps to enhance the ideas on wimax physical layer.
