基于中位点的分层匹配算法

Layered Matching Algorithm Based on Median

提出一种基于中位点的图像分层匹配算法。计算2幅待匹配图像的中位点,以这2个中位点为参照对图像的特征点进行分层。在对应各层之间分别构造高斯权Laplace矩阵,由SVD分解的结果构造反映特征点之间匹配程度的关系矩阵。根据该关系矩阵实现对应层之间的特征点匹配,得到整幅图像的匹配结果。实验结果表明,该方法具有可行性和有效性。

This paper offers image layered matching algorithm based on the median.It figures out the median of each image,constructs the Gauss-Laplace matrix corresponding to every lay respectively,conceives the related-matrix being true of the match level which accord to each feature point by the result of SVD analysis.It obtains the matching result of the entire image by the feature points matched.Experimental results demonstrate the feasibility and effectiveness of the approach.
