关于沙威老师的CS_MRI_demo matlab代码，该程序可用于核磁共振成像，希望对大家有用(CS_MRI_demo matlab code, the program can be used for nuclear magnetic resonance imaging, we hope to useful)

50hz线电滤波算法，剔除信号中的限电干扰(50hz power line filtering algorithm, brownouts eliminate signal interference)

Junit Instrumentation test case for camera power measurement.

说明：  本文设计了一款人体行为异常监控系统，主要适用人群是老年人，在摄像头固定的情况下，自动检测人体运动轨迹，并与提前设定好的行为库进行匹配，分析判断是否具有异常行为。 在数字图像预处理部分采用了图像二值化，腐蚀与膨胀等几种方法为人体目标的跟踪和检测做准备。为了克服在实际操作中遇到的问题，采用了帧差法和ViBe算法，帧差法即利用帧间变化与当前帧、背景算法来判断它是否大于阈值，并分析视频中序列的运动特性，ViBe算法则是一种背景建模的方法，背景模型是由邻域像素来创建，并对比背景模型、当前输入像素值检测出前景，确定视频中的目标跟踪。在人体行为识别中，运动目标最小长宽比以及连续帧间的加速度来判断人体行为是否异常，如果检测到异常的行为比如说摔倒、快跑等行为，在识别的过程这种实时监测。不同环境可能需要调试，要求有一定编程基础，小白慎入。(In this paper, a monitoring system for abnormal human behavior is designed, which is mainly applicable to the elderly. When the camera is fixed, it can automatically detect the human motion track and match with the behavior database set in advance to analyze and judge whether there is abnormal behavior.)

说明：  SAR雷达模拟的PPT，讲述SAR雷达回波模拟的具体原理，实现方法，和仿真结果(SAR)

因而本文基于MATLAB 针对Nakagami 衰落信道仿真了它的统计 特性,包括接收信号的复包络模拟和在具有最大比合并分集下的电平通过率及平均衰落持续时间的性能分析。重点在于理解和建立采用 MATLAB 进行信道信真的方法及对Nakagami 衰落信道本身统计特性的理解。(Based on MATLAB which Nakagami fading channel simulation for its statistical properties, including the received signal complex envelope simulation and has the maximum ratio combining diversity under the level crossing rate and average fade duration of the performance analysis. Emphasis is on understanding and the establishment of the channel using MATLAB and the letter is really way Nakagami fading channel statistical characteristics of their own understanding.)
