A New Moment Method for Geometry Recognition
Wang Liang · Mechanical Science and Technology · 2002
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.
