说明：  实现了pcm调制的全过程的MATLAB仿真，包括调制、A率压缩、量化、解扩、解调、信号恢复。(Modulation achieved pcm MATLAB simulation of the whole process, including the modulation, A rate of compression, quantization, despreading, demodulation and signal recovery.)

说明：  课程中的图像处理实验matlab编程，有助于学习图像处理的初学者(program of matlab image processing , helpful for beginners of image processing)

说明：  本文实现了在连续视频数据流中几种不同的运动检测算法，他们都是基于当前帧图像和前一帧图像的比较，程序使用了AForge.NET framework库。其中的示例代码支持下面几种视频格式：AVI文件、网路相机的JPEG和MJPEG，本地的采集设备(USB相机等)。(This article implements a continuous video data stream in several different motion detection algorithms, they are based on the current frame and previous frame image comparison, the program uses the AForge.NET framework library. Sample code which supports the following video format: AVI file, network camera JPEG and MJPEG, the local collection devices (USB cameras, etc.).)

曲线波变换用于图像去噪可以很好的解决物体沿曲线边缘的特性，本算法基于USFFFT，可以更高效的进行去噪(Curvelet transform for image denoising can solve problems well along the curve edge features, the algorithm based on USFFFT, can be more efficient denoising)

神经网络是单个并行处理元素的集合，我们从生物学神经系统得到启发。在自然界，网 络功能主要由神经节决定，我们可以通过改变连接点的权重来训练神经网络完成特定的功能。如人脑的某一部分进行机械记忆特别有效 而某一部分进行抽象思维特别有效。(Nervous system has some functions. Here I make them by using Matlab.)
