摘要
本文采用多种匹配模式进行下视景象的匹配 ,利用小波分解生成多分辨率影像、提取边缘特征作为匹配的基础 ,同时文中改进了一种小波兴趣算子来生成兴趣特征图像 ,并用于初匹配。通过试验及统计 ,分析了不同匹配模式的效果 ,以及多种模式相结合对下视景象匹配的改善。
Multi-matching modes are used on scene matching in this paper. The multi-scale pyramid image is obtained by wavelet decomposition. Then based on the decomposition result, edge features are extracted, and an interested algorithm was developed to make an interesting feature image that used on primary matching. Through the experiment and statistics, the paper analyzed the results of different matching modes and the results improvement by different combination of matching modes.
