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 )

Centroid
WSN 质心定位算法 Centorid Algorithm
加经典参考文献
A: 如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
未知节点利用邻居锚节点进行定位,没有邻居锚节点的未知节点无法定位。
B:
如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
未知节点一旦被定位就充当起锚节点的功能,向周围邻居发送自己的估计坐标信息
未知节点把已经定位的未知节点与锚节点同等对待
C:
如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
有邻居锚节点的未知节点只利用邻居锚节点进行定位,没有邻居锚节点的未知节点才利用已经定位了的邻居未知节点进行定位。(WSN centroid localization algorithm Centorid Algorithm
A: If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Unknown node using the neighbor anchor nodes to locate, no neighbors anchor nodes and unknown nodes can not be located.
B:
If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Unknown nodes are positioned on as soon as the function of anchor nodes to send their neighbors estimated coordinate information
Unknown unknown node to node already positioned anchor nodes treated equally
C:
If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Of the unknown neighbor anchor node the neighbor nodes are only positioned anchor nodes, )

CLASS_facepipe
实现人脸特征定位及人脸描述符提取功能。很好很强大。(
To get started, run "demo". This detects faces in the example
image, loading cached detections from files if available,
localizes the facial features and extracts descriptors for each
face.)
