查询词典 matching

A new measure named invariant linear moment for image matching is introduced and proved in this paper .

介绍一种新的景象匹配的度量测度：不变线矩。

In the matching stage, the angle of feature vectors is used as the similarity measure in the high dimensional space directly. This similarity measure is invariant to the linear transformation of feature vectors. Compared with SIFT and normalized correlation, the proposed method needs no primary features such as edges, corners, gradient or shapes which are very unstable in low contrast and low NSR images.

在匹配过程中，以向量之间夹角的大小作为相似度度量，直接利用图像的灰度信息在高维向量空间中考虑图像之间的相似度，克服了在低照度、低信噪比的图像中求边缘、角点、梯度和形状等特征的困难，不受向量模大小以及向量平移的影响，即相似度的计算是线性光照不变的。

We analyze the application range of conventional matching filter in timelapse seismic crossequalization. The result indicates that this method can work very well when the inverse operator of the filter is the minimum phase.

分析了用于时移地震互均衡处理中的传统匹配滤波算法适用范围，结果表明该方法在滤波算子的反算子为最小相位时效果最好。

In this paper, we study the matching of security investment portfolio and its investment strategy in china.

内容提要：本文提出并实证检验了我国证券投资基金投资组合的构建和调整与其投资策略匹配性的研究视角。

In addition to iodide and iodate, another iodine compound could be separated and detected in certain samples with high total iodine concentrations and was identified as elemental iodine, probably in form of triiodide, by peak matching.

在碘化合物总浓度很高的特定样品中，除了碘化物和碘酸盐，其他的碘化合物也可以被分离和检测，其通过峰匹配以三碘化物形式被做为元素碘检出。

The main contributions of the thesis are as follows: Using invariants and matrix theory, especially the special properties of eigenvalues and eigenvectors of the so called irreducible matrix, we put forward several effective new algorithms for the complete matching problem under Euclidean transformation, similarity transformation and general affine transformation.

论文的主要贡献如下：利用不变量和矩阵理论，特别是巧妙地利用了不可约矩阵的特征值和特征向量的特殊性质，提出了求解欧氏变换、相似变换和一般仿射变换下完全匹配情形的点模式匹配问题的几种非常有效的新算法。

Now, he said, Islamabad expects a matching response from Afghanistan.

他说，现在伊斯兰堡期待来自阿富汗的相匹配的反应。

The algorithm transforms the subgraph isomorphism problem into a matching problem between vertexes through the introduction of similarity features for every vertex.

通过单个顶点的相似度特征，将子图同构问题转化为顶点之间的匹配问题。

Then, by taking the local features provided by users as portions of the AAG, and the whole CAD model as the whole AAG, the problem of local feature matching is transformed into that of subgraph isomorphism. Subgraph isomorphism is a NP-complete problem.

在局部匹配过程中，用户输入的局部结构被表示成"子图"，待匹配的整体CAD模型被表示成"大图"；则在整体CAD模型中，检索局部结构的问题就被转换成在"大图"中寻找同构"子图"的问题。

In this paper, an isotropic resolution down-looking scene matching algorithm based on SNN kernel method has been proposed.

摘要提出一种基于核方法的下视等分辨率景象匹配算法。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
