1) descriptor
[英][dɪ'skrɪptə(r)] [美][dɪ'skrɪptɚ]
描述子

2.
Attributes Reduct and Decision Rule Optimization Based on Descriptors in Information Systems;
基于描述子的信息系统属性约简及决策规则优化
3.
The MEDV descriptors can be calculated through a relative electronegativity and a relative distance of the substituted aromatic compounds atoms.
根据非氢原子类型分类、基于非氢原子相对电负性和非氢原子间距离等进行计算得到的分子电性距离矢量(MEDV)为描述子,对取代芳烃的结构进行表征。
2) VSGETAWAY
VSGETAWAY描述子
3) SVRDF
SVRDF描述子
1.
To establish a new amino acid structure descriptor that can be applied to polypeptide quantitative structure activity relationship (QSAR) studies, a new descriptor, SVRDF, was derived from a principal components analysis of a matrix of 150 radial distribution function index of amino acids.
研究结果表明,SVRDF描述子能够系统地表征肽与生物活性相关的结构信息,有望成为多肽定量构效关系研究中一种有效的结构表征方法。
4) V-system descriptor
V描述子
1.
In this paper,we present a novel V-system descriptor for 2D models;the descriptor is invariant against the rotation,translation,scale transform,and can remove the effect of the arbitrary start point of the shape through the principal orientation.
提出了一类新的V描述子,对二维图形进行V变换提取形状信息,并定义归一化后的变换系数为描述子,其具有旋转、平移、缩放不变性,通过形状主方向在一定程度上消除了起始点的影响。
5) Zernike descriptor
Zernike描述子
1.
By the approach,we first obtain orthogonal projections of the 3D models which contain the depth information of the models,and then we get similarity among 3D models through matching the shape similarity among orthogonal projections in terms of both Zernike descriptor and Reeb graph.
首先计算三维模型的带深度信息的正交平面投影图像,然后采用Zernike描述子和Reeb图比较这些正交投影图像的形状相似性,最后通过正交投影图像的形状相似性来获得三维模型的相似性。
