粒子群算法是求解函数优化问题的一种新的进化算法,然而它在求解高维函数时容易陷入局部最优,为了克服这个缺点,提出了一种新的粒子群算法,算法对粒子的速度和位置更新公式进行了改进,使粒子在其最有位置的基础上进行位置更新,增强了算法的寻优(PSO for solving function optimization problems is a new evolutionary algorithm, but it is easy to solve high-dimensional function into local optimum, in order to overcome this shortcoming, a new particle swarm algorithm, algorithm on the particle velocity and location of the update formula has been improved, so that particles in the most positions on the basis of location updates, enhancements, optimization algorithm)

图像配准定义为:对从不同传感器、不同时相、不同角度所获得的两幅或多幅图像进行最佳匹配的处理过程.图像配准需要分析各分量图像上的几何畸变,然后采用一种几何变换将图像归化到统一的坐标系统中。在配准过程中,通常取其中的一幅图像作为配准的标准,称之为参考图像;另一幅图像作为配准图像(Image registration algorithm)
