Algorithm of aerial films recognition based on moment invariant

LI Ying\|chun 1,2 CHEN He\|xing 2,YANG Jian\|bo 1,LIN Lin 3 (1.College of Commun. Eng.,Jilin University,Changchun 130012,China; 2.The Second Aeronautical Institute of the Air Force,Changchun 130022,China: 3.School of Information Eng.,Beijing In  
A new method which recognizes the aircraft models in aerial film according to the symmetry feature of aircraft is addressed. This method is based on moment invariants theory and selects CG(Center of gravity)as original point. With three basic invariable features including the ratio of length and width, the projected value of X\|axis, the projected value of Y\|axis, all kinds of aircrafts can be recognized. This method which can identify the target with little computation and high speed is proved effective. In the experiment, the ratio of aircraft recognition reaches 100 percent.
