摘要: 针对投影图像的形状特征,结合傅里叶描述算子、Zernke不变矩、形状参数、离心率的特点,提出一种基于权重关系的合成的形状特征描述算子,将其应用到3D模型投影图像检索算法中。实验结果表明,相比其他4种形状特征描述算子,该算子能较好描述投影图像的轮廓、区域以及整体特征信息,并可提高算法的检索效率。

Abstract: Aiming at the shape feature of projection image, this paper proposes a hybrid shape feature description operator based on weighted relationship by combing different shape characteristics from Fourier description operator, Zernke moment invariant, shape function and eccentricity, and makes it use of 3D model projected image retrieval algorithm. Experimental results show that the operator can well describe contour, region and whole feature information of projected image compared with other four kinds of shape feature description operator, and it can enhance the retrieval performance for algorithm.

Key words: 3D model retrieval, visual similarity, shape feature description operator
