PCA的步骤:
1 先将数据中心化;
2 求得的协方差矩阵;
3 求出协方差矩阵的特征值与特征向量;
4 将特征值与特征向量进行排序;
5 根据要降维的维数d’,求得要降维的投影方向;
6 求出降维后的数据;
(PCA steps: 1 of the first data center 2 covariance matrix obtained 3 obtained covariance matrix eigenvalues and eigenvectors 4 eigenvalues and eigenvectors will be sorted 5 according to the dimension of dimension reduction d ' , seek to reduce the dimension projection direction 6, the data obtained after the dimensionality reduction )

MST-Player-v1.5
运动目标识别,采用背景差分方法。背景图像由均值法获得。里面的视频换成前几帧换成纯背景效果能更好一点(Moving target identification, using the background difference method. Background image obtained from the mean. Which replaced the previous video frame replaced by pure background a little better results)
