| 摘 要： | 针对电视制导系统图像匹配时遇到的大比例目标遮挡以及严重噪声干扰等情况,提出一种基于分割模板加权Hausdorff距离(HD)矩阵的特征匹配算法.将模板分割为若干个子模板；利用最小核相似区检测角点( SUSAN)算子提取图像的角点；分别计算子模板与搜索图像对应区域的基于角点响应函数的加权HD,构造出HD矩阵；经过角点密度...

| Abstract: | A feature matching algorithm based on template partition Hausdorff distance matrix was proposed to resolve the problems of large scale target occlusion and serious noises in TV guidance process.The template image could be divided into several sub-templates and the corners were detected by using SUSAN operator.Hausdorff distance matrixes between sub-templates and searching image were constructed by calculating weighted Hausdorff distance based on the corner response function.Corrected by corner density matri... |
