摘要
简单介绍了惯性矩理论 ,定义了最小包络矩形 ,提出惯性比概念 ,惯性比 μ无量纲 ,μ∈ [0 ,1]且惯性比具有移动、旋转不变性。利用最小包络矩形和惯性比可以唯一标识一个几何图形 ,为布局问题 ,图像识别等需要进行几何匹配场合提供了简单明了的特性。
This paper introduces the theory of moment,defines minimum enclosed rectangle, and brings forwards a new concept--ratio of inertial moment. The ratio of inertial moment μ has no measure, and μ∈. it has the features of translation invariance and rotation invariance. The paper discusses how to use ratio of inertial moment and minimum enclosed rectangle to express a geometry and its probability,it can be used in the layout design and the image recognition where geometrical shape match is needed. Some theorems and examples are given.
