DISCRETE MOMENT INVARIANT ALGORITHM AND ITS APPLICATION ON TARGET RECOGNITION
-
摘要: 該文分析了在離散狀態(tài)下不變矩特征受比例因子變化的影響,提出了一種修正歸一化中心矩的方法,保證了不變矩特征具有平移、旋轉(zhuǎn)和比例因子的不變性,并將此用于目標(biāo)識(shí)別,最后通過仿真實(shí)驗(yàn),比較了修正前后的識(shí)別率,表明本文采用的方法是行之有效的方法。

Abstract: The paper analyses the influence of scale factor on discrete moment invariant characteristics. A modified attributive center characteristics with scale, translation and rotating invariances are proposed. The moment invariant characteristics are used in target recognition. Finally through simulation, its recognition rate with that before modification is compared. The results show this way is feasible. -
