High Speed Face Recognition Based on Discrete Cosine Transforms and Neural Networks

系统可以利用声音信号产生带有回声的声音文件，并可以从带有回声的文件中消除回声而得到原声音信号；另外，系统还能从中估计反射物的距离(System can make use of the voice signals of the sound files with echoes and echoes from the document with echo and obtain the elimination of the original voice signal In addition, the system can also have to guess the distance from the reflective material)

QPSK for AWGN and Rayleign fading channel example

说明：  滑模控制，基于速度环的控制改进算法，滑模控制是变结构控制，又是非线性控制算法，应用于电机领域(Sliding mode control is an improved control algorithm based on speed loop. Sliding mode control is a variable structure control and a non-linear control algorithm, which is applied in the field of motor)

matlab图像处理实例详解第三章源码程序，推荐大家一起学习，很好很实用。(Detailed examples matlab image processing Chapter III source program, recommend everyone to learn, very very useful.)

tv模型代码,用到的偏微分方程技巧和各项异性扩散(tv model code, techniques used in partial differential equations and anisotropic diffusion)

空间后方交会程序，已知地面点坐标及对应像点求相机位置和姿态。( Space resection procedure, known ground point coordinates and the corresponding image point for camera position and posture.)

自适应控制中，用Matlab算法实现带遗忘因子递推最小二乘参数估计(Forgetting factor recursive least squares parameter estimation)

说明：  基于MATLAB的树叶图像特征分类识别，图像分析处理 分割 特征提取 分类识别等 (MATLAB-based leaf image feature classification, image analysis and processing, such as segmentation feature extraction classification)

该程序是一纯滞后系统的大林控制算法，是一种不同于常规PID控制规律的新型算法。其控制效果大大优于普通PID控制算法。(that the procedure was a pure delay system Dalin control algorithm, Unlike a conventional PID control algorithm for the new law. Its effectiveness is significantly better than ordinary PID control algorithm.)
