由于选用部分Hausdorf距离进行图像匹配时不能满足较大尺寸图像匹配实时性要求，利用了多级分层匹配技术加速图像匹配，本文提出了多级实时图像匹配算法，该算法以部分Hausdorf距离为图像匹配相似性度量，结合小波变换多分辨率思想提取多尺度图像特征，实现了由粗到精多级分层实时匹配。-As part of the Hausdorf distance used for image match the larger size can not meet the requirements of real-time image matching using a multi-layered image matching technology to speed up matching, this paper proposes multi-level real-time image matching algorithm for the image to part of the Hausdorf distance matching similarity measure, combined with ideological and extract multi-resolution wavelet transform multi-scale image features, achieved by the coarse to fine multi-layered real-time match.
