| 摘 要： | 提出三维正交样条矩的定义,并将其应用于三维模型检索.作为一种正交多项式函数系,正交样条函数结合球面调和函数所定义的矩具有正交性等优良性质.样条函数的局部性对于突出模型的局部特征有较好的效果.实验结果表明,三维正交样条矩优于三维小波矩,具有更高的检索效率.

| Abstract: | 3D orthogonal spline moments are defined,and used for 3D model retrieval.As a kind of orthogonal polynomials system,orthogonal spline function has many good properties such as orthogonality and locality.So orthogonal spline moments can adequately express the local property of model.Extensive experiments show that the 3D orthogonal spline moments are of higher discriminating power. |
