Based on the real-time image sequence of airborne, a novel vision-based integrated navigation method of UAV which combined the relative and absolute navigation algorithms is proposed. Visual odometry is used as the relative algorithm in order to estimate the position of UAV by the derived homography matrix between two consecutive images. RANSAC algorithm is working to remove mismatching points. To...
Flooding is the base of unstructured P2P(Peer to Peer) systems, such as Gnutella. Pure flooding mechanism doesn't be used in practice for a great amount of redundant generated during query propagated among network. Studies show rates of redundant messages generated are not equal in different stage, as the distance of the query propagated increase, the number of redundant message exponential growth...
