摘要： 当前多数遥感图像融合算法主要是依靠比值法选取全色图像或多光谱图像中的其中一个高频子带作为高频融合系数,忽略了另一个高频系数所包含的信息,易导致融合图像出现模糊以及光谱失真等不足.对此,本文提出了基于非下采样Contourlet变换与锐度制约模型的遥感图像融合算法.通过亮度-色调-饱和度(IHS)变换 ...

摘要： 按需矢量路由(AODV)是移动自组织网络(MANET)的典型路由,然而AODV路由总是选择最短路径进行通信,这会引起网内流量的不平衡,可能也会引起拥塞问题,最终影响服务质量(QoS)。为此,提出基于AODV的权值路由方案,记为AODV-W。AODV-W路由考虑了路径传输时延、链路稳定性和节点能量,并 ...
