首先将场景图像进行滤波处理达到去噪效果,然后通过特征描述符降维以减少计算量,再通过RANSAC对基于SIFT的特征点匹配进行误匹配的剔除,最后使用PSO算法进行优化以寻找到最佳的Ratio值。通过在模糊、较暗、较亮和遮挡4种以机械手为背景的场景下的图像,进行4种算法的对比实验,最后表明SIFT特征匹配算法的误匹配率最小,精确...
% Particle swarm optimization (PSO) is one of the modern heuristic algorithms that can be applied to continuous and discrete optimization problems. % The original binary PSO (BPSO) has got some disadvantages that make the algorithm not to converge well. % To deal with these disadvantages, a ne...
The achieved results show that the proposed PSO algorithm is able to save sensors energy when compared to the common deployment of nodes with a single transmission power.随着物联网(IoT)成为现实,出现了能源受限节点和网状网络固有的几个问题。其中一个问题与网络每个节点的最佳传输功率有关,整个网络都...
