摘要
针对传统均值金字塔搜索算法存在起始点不定,搜索范围缺乏约束的问题,利用小波分析的多分辨率特性,构建了小波边缘金字塔上的快速图像匹配算法.首先对低分辨率的边缘图像进行匹配操作,然后逐级上推,最终实现全分辨率下的图像匹配,实验结果表明,该算法可以减少计算量,显著提高匹配效率.
Based ou multi-resolution character of wavelet transform, a fast image matching algorithm on the wavelet of pyramid edge was pro- posed for the problems of what point to start in conventional mean pyramid structure search algorithm and the lack of restrictions in search range. The low-resolution edge image was matched on the match result,which was implemented stepwise up to the full-resolution image match. The results showed that the algorithm can reduce the calculation amount and improve the efficiency distinctively.
