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, )

在本演示中，一个简单的图像检索方法，提出基于图像的颜色分布。用户只需提供一个“例子”的形象和搜索是基于这个例子（例如基于查询的图像）。包括图像和教学指令!!!(In this demo, a simple image retrieval method is presented, based on the color distribution of the images. The user simply provides an "example" image and the search is based upon that example (query by image example). Experiment image and instruction included!!!)
