摘要
为实现图像自动配准,需要确定初始变换参数,为此提出图像特征线和图像特征圆的概念,基于仿射变换模型,推导了确定图像自动配准初始参数的算法,并基于B样条小波和混合遗传算法求取最终的多源图像配准参数.实验结果表明,该算法可实现图像的自动配准,证明了该算法的有效性.
Initial transform parameters must be confirmed firstly to realize automatic image registration. The conceptions of im age character line and image character circle were defined, and the algorithm determining initial parameters of automatic image registration was derived based on affine transform model. B spline wavelet and hybrid genetic algorithm were used to work out the final multi-source image registration parameters . Experi ments show that the proposed algorithm can realize automatic image registration, which verifies the effectiveness of the algo rithm.
