基于小波零交叉基元的多分辨率图像匹配方法

文中将小波变换运用到立体视觉的图像匹配中，选取合适的二进小波基，以二进小波变换的多尺度零交叉为匹配基元，较多地利用了图像的结构特征。在匹配过程中采用由粗到精的层决匹配策略和严格的匹配约束，减小了对应点搜索范围，并从局部和整体两个角度进行匹配后的质量控制。实验结果证明，该方法具有较高的匹配精确度和较快的匹配速度，并且算法稳定。

Multiresolution image matching algorithm using zero-crossing of wavelet transform

In this paper, an algorithm for image matching which utilizes the wavelet transform was proposed. A binary wavelet radicle was selected and the multiresolution zero-crossing of binary wavelet transform was used as matching primitive. This algorithm used more structure features of the image. The matching strategy from coarse-to-fine and strict constraints were used to reduce the searching area. The quality control after matching was carried out also. Experiment shows that the algorithm is reliable and stable in operation, and has high accuracy.
