In this dissertation, a new face representation algorithm based on weighted DCT fusing global facial feature and local facial feature is proposed.
本文基于DCT变换，给出了一种融合人脸整体特征和局部特征的加权DCT人脸表征算法。
Two kinds of features, global context feature and local context feature, are proposed as the classification features.
本文提出了全局上下文属性和局部上下文属性两类属性作为分类模型的特征属性。
Because the proposed angular feature is invariant to rotation, translation and scale transformation, the registration result will converge to global minimization rather than local one.
由于本文提出的角特征不随旋转、平移和尺度的变化而变化，所以配准最终收敛到全局最小值，而不是局部最小值。
By study of the existing extraction and representation algorithm of motion information, a practicality module is designed and implemented mainly on global and local motion feature extraction.
通过对运动特征提取算法进行研究，设计并实现了一个实用的全局运动特征和局部运动特征提取模块。
The geometrical features that combine facial global features with local ones are chosen in this dissertation. And they are composed into a one-dimensional feature vector.
本文选取人脸总体和部分相结合的几何特征，并组成一个一维特征矢量。
In the local or global movement of rock mass under mining, overlying strata play a key role. The overlying strata movement is a complicated space-time process and has time-dependent feature.
上覆岩层对采动岩体活动全部或局部起决定性作用，上覆岩层运动是一个复杂的时空过程，具有时效性。
