三维极半径矩及其在三维模型检索中的应用
3D Polar-Radius-Invariant-Moments and Their Application to 3D Model Retrieval
【摘要】 提出一种用于三维数据模型检索的三维极半径矩.证明这种矩具有平移、缩放和旋转的不变性.给出18个不变矩表达式,可用于三维模型的比较和识别.实验验证特征向量的不变性.并且,基于这种三维极半径矩的识别算法具有较好的识别率.
【Abstract】 A novel moment,3D polar-radius-invariant-moment,is proposed for the 3D object recognition and classification.Some properties of the new moments including the invariance on shift,rotation and scale transforms are studied and proved.Eighteen moment invariants are derived and tested. Examples are presented to illustrate the performance and invariance of these moments.With the help of these moment invariants,the 3D models are distinguished accurately.
