The existing video jitter detection algorithms only calculate parameters such as displacement, rotation angle, zoom scale. The lack of extent calculation of jitter leads to wrong judgments while faced with complications. To tackle the problem, the longest path based algorithm for extent estimation of jitter was proposed in this paper. First, global motion estimation was conducted by gray projection...
The multicast routing model is set up by hybrid routing protocol, Aiming at the mobile network topology and the characteristics of multicast routing based on QoS. A multicast tree meeting the QoS constraints, consumption tend to a minimum and stable form is set up based on ant colony algorithm. Experiments show that the algorithm has a better performance than the other algorithm.
For the search of the optimal path and the establishment of the multicast tree which meets QoS constraints in multicast routing, an improved ant colony algorithm is proposed in the paper. In the searching process, two group ants carry out searching separately and alternate information after one search to avoid stagnation. And the optimal one is selected from the two paths combining multi-constrained...
A new algorithm based ant colony optimization for QoS (quality of service) mobile multicast routing is proposed in the paper. According to the scope of search paths, a suitable orthogonal table of the orthogonal experiment is implemented, and the effect of every QoS parameter is confirmed. Meantime, An improved measure is taken to control the volatility of pheromone dynamically, and the optimal tree...
