| 摘 要： | 研究了多模态医学图像配准的一种，即多光谱图像的配准，分析了该配准存在的困难：运算量巨大，速度较慢，占用内存多，提出了用parzen窗口函数来估计概率密度，以及用样本平均来估计熵；在搜索策略上采用了快速有效的模拟退火算法。实验证明，本文的方法很好地解决了多模态配准中存在的问题，能够快速稳定地实现多光谱图像的配准。

| Abstract: | Registration of multi-spectrum image was studied.To solve the problem in this kind of registration,we proposed to approximate the underlying probability density by using Parzen Window density estimation and estimation entropies by a sample mean.Simulated annealing searching method was used,which was fast and robust.Our experiments illustrate that the method used in this study can align multi-spectrum image quickly and stably. |
