摘要
提出一种基于小波的多尺度分析的图像特征点提取方法,给出了一种多分辨率分块特征点匹配的图像检索方法,多分辨率的分块策略使得相关反馈的自适应性得到了更好的保证,从而实现图像的快速、准确匹配。实验表明该方法在计算时间和精度上都是十分有效的。
Present an approach of image feature point extraction based on wavelet multi-scale analysis. Besides, the technology of rele-vance feedback was combined with the algorithm presented in the paper to enhance the effectiveness of retrieval.Consequently it can realize image matching quickly and exactly. Experimental results show that this method is effective.
