目的像对稠密匹配是视觉定位、影像融合、超分辨率重建等高级图像处理技术的基础,由于像对可能受多种摄影条件的影响,导致难以获得高效的稠密匹配结果,为此提出一种结合密度聚类平滑约束与三角网等比例剖分的像对稠密匹配方法。方法为了快速获得同名点集,采用ORB(oriented FAST and rotated BRIEF)算法获取稀疏匹配点集,利用积分图筛选出以该特征点为中心的邻域中密度直达的特征点数目,计
In this paper, the transmission performances are studied in cognitive radio networks with primary user emulator and relay existence. In the proposed network, th
