使用混合高斯背景建模方法，进行视频中运动物体的检测。视频采用matlab自带的视频。适用于背景静止的视频。会用方框框出运动物体，阈值可自行调节。含实验报告。课程实验，仅供参考。

本人花了几个月做的单相电能表程序,已经在线上生关了，非常珍贵的资料。

基于种群分解，使用主元分析进行聚类分析和种群生成，种群进化使用NSGA-II选择机制，

常用的温度检测元件主要有热电偶、热电阻、热敏电阻等。热电偶主要是利用两种不同金属的热电效应，产生接触电势随温度变化而变化，从而达到测温的目的。测量准确，价格适中测温范围宽，线性度较好。但其输出电压受冷端温度影响，需要进行冷端温度补偿，使电路变得复杂，在本题中并非最佳方案。 热敏电阻由金属氧化物或半导体材料制成，灵敏度高、热惰性小、寿命长、价格便宜。但其测量的稳定性和复现性差，测量精度无法满足本题发挥部分0.2℃的要求。而且线性度差，需要进行查表线性拟合，大大浪费控制器的资源，因此不能选用。 热电阻是利用金属的电阻率随温度变化而变化的特性，将温度量转化成电阻量。其优点是准确度高，稳定性高，性
