Based on research of π-block in a quotient group, we characterize some π-separable groups using some related sufficient conditions of a π-block, which extend the related results in modular representation theory of p-solvable groups. 根据商群的π-块理论,用π-块论条件刻画几类π-可分群,推广了一些p-可解群上的模表示论结果。
This correspondence firstly gives comprehensive study to fast algorithms for geometric moments, including image transform, Delta method, computation via corner points, method based on Green ′ s theorem and image block representation. 对规则矩快速算法了进行了综述,包括图像变换、Delta方法、拐点方法、Green定理法和图像块表示法。
In contrast to the traditional block based matching technique, the motion estimation in the object-oriented compression approach should be consistent with a representation of a scene in terms of objets. 同经典的基于块的匹配技术不同的是,面向对象编码技术中的运动估计应该与景物的对象表示相一致。
Firstly, the ERPs image is combined by single experiment signals. Secondly, the block operation is adopted to utilize the similarity between these blocks, which is used to reconstruct the signal in the framework of sparse representation. 首先,将单次实验信号组合形成ERPs图像,然后对其进行取块操作,利用图像块之间的相似性,在稀疏表示的框架下进行最佳信号重建以达到去噪效果。
The creative development is based on deep understanding the relationship between Holistic View of language and the Block of mental representation. 而这种创造性发展正是基于对语言分析的整体观和心理表征的组块性特征之间关系的深入认识,客观上惠及语言教学应用。
So as to enhance the resolution of covariance matrix, by introducing the conception of block combination into the matrix representation, and using SURF description for reference, the paper presented a new feature vector form. 为了提高协方差矩阵的可分辨性,本文将分块思想引入到目标的协方差矩阵表示中,并借鉴SURF特征描述,改进了特征矢量的表示形式。
