基于直线基元角方向对几何关系直方图的目标识别方法

An ATR Method Based on Newly Defined Pairwise Geometric Histogram

针对以往"角方向对几何"同类技术[6～8]提出了新的基于直线基元的几何不变特征关系,并使用该关系针对目标线集建立特征关系多维直方图,作为目标的几何不变特征,通过多维直方图匹配进行目标识别。实验证明该模式关系对于较规则的形体,其检测精度优于以往方法,可用于基于内容与结构的图像分析与目标识别系统中。

The paper presents a new defined pairwise geometric invariant relationship of the line segments of the shape targets based on the formal work of this technology. The method recognizes the targets by comparing the multi-dimensional histograms which are formed by the new defined invariant relationship. The experiments show that the new relationship is more accurate for regular shape recognition than the old methods.
