| 摘 要： | 为了有效地确定目标位置,提出了一种基于兴趣点检测的目标识别方法.根据像素点的灰度和边缘强度信息,确定兴趣点的分布位置.以兴趣点为中心,利用位势函数构建目标函数,目标函数取最大值的位置确定为目标位置.提出了一种改进的概率混沌优化算法求解目标函数的最大值.概率混沌优化算法将搜索空间分为原始搜索空间和精搜索空间,分别以不同的概率同时对两个空间进行搜索,并逐渐增大精搜索空间的搜索概率,从而可在确保算法具有全局寻优能力的前提下加快寻优速度.研究结果表明,该方法可有效地确定目标位置,且结果不受目标平移、旋转、缩放、甚至变形等影响,仿真结果验证了该方法的有效性.

| Abstract: | A new target detection algorithm based on interesting points is proposed to determine the position of the target effectively.The interesting points are determined according to its gray and edge information.An object function is constructed by potential functions whose centers are the interesting points.The target position is determined where object function is max.A probability chaos optimization algorithm is proposed to optimize the object function.The fine searching space and the origin space are searched... |
