GMM高斯混合模型进行背景建模（Matlab）
转：https://blog.csdn.net/jinshengtao/article/details/26278725
混合高斯背景建模是基于像素样本统计信息的背景表示方法，利用像素在较长时间内大量样本值的概率密度等统计信息(如模式数量、每个模式的均值和标准差)表示背景，然后使用统计差分(如3σ原则)进行目标像素判断，可以对复杂动态背景进行建模，计算量较大。
在混合高斯背景模型中，认为像素之间的颜色信息互不相关，对各像素点的处理都是相互独立的。对于视频图像中的每一个像素点，其值在序列图像中的变化可看作是不断产生像素值的随机过程，即用高斯分布来描述每个像素点的颜色呈现规律单模态(单峰)，多模态(多峰)(Gaussian mixture background modeling is a background representation method based on the statistical information of pixel samples. Statistical information such as the number of patterns, the mean and standard deviation of each pattern are used to represent the background. Statistical difference (such as 3_principle) is used to judge the target pixel. Complex dynamic background modeling has a large amount of computation.
In the Gaussian mixture background model, it is considered that the color information between pixels is uncorrelated and the processing of each pixel is independent of each other. For each pixel in a video image, the change of its value in a sequential image can be seen as a random process that produces pixel values continuously, i.e. Gaussian distribution is used to describe the regularity of color rendering of each pixel in single mode (single peak) and multi-mode (multi-peak).)

check_form
表單驗證
調用為
onBlur=checkform(fname1,fname2,types,value1,value2)
輸入框的驗證
onSubmit subt(this.id)
表單提交時的驗證
兩者需要一起使用
fname1=驗證的項目名
fname2=驗證的副項目名
types=驗證的方式
value1=驗證的值1
value2=驗證的值2
驗證的方式值:(多驗證方式用"|"分割 例: 1|2|3)
0.該值不能為空!
1.您輸入太短了!不能小於value1字符
2.您輸入太多了!不能超過value2字符!
3.你的兩次密碼不一至,請驗證!
4.您的輸入與要求不相符,該輸入只能在value1~value2之間!
5.您輸入的E_mail不正確!請重新輸入!
6.只能為數字
