【摘要】 配准的目的就是将同一场景的不同图像对齐或匹配,消除存在的几何畸变。介绍一种基于移动向量估计的图像配准技术,它利用复小波变换相对传统小波的一些优点,如位移不变性、多方向选择性,对移动向量进行估计。实验结果表明,使用这种方法对消除几何畸变有很好的效果。更多还原

【Abstract】 The goal of image registration is to align or match different images of the same scene and remove the potential geometric distortion existed. An algorithm of image registration based on motion vectors estimation was proposed. The algorithm takes advantage of complex wavelet transform (CWT) over the conventional wavelet transform, such as shift-invariance and better directional selectivity, to estimate motion vectors. The experimental results demonstrate that our proposed algorithm has very good performance in removing geometric distortion.更多还原
