针对医学图像配准问题,提出了一种改进的混合算法。基于普通Powell算法,在其中加入遗传算法进行改进,利用遗传算法全局搜索能力好的特点对Powell算法进行优化。并通过实验论证,证明了使得其配准精度和速度均得到了提高,从而验证了本算法的有效性。
Aiming at the problem of medical image registration, an improved hybrid algorithm is proposed. Based on the ordinary Powell algorithm, genetic algorithm is added to improve Powell algorithm and the global search ability of genetic algorithm is used to optimize Powell algorithm. The experimental results show that the registration accuracy and speed are improved, which proves the effectiveness of the proposed algorithm.
