An iterative factorization method based on linear subspace for projective reconstruction is presented in the paper. It relies on the facts that the rows in the matrix including all the image points span the same linear subspace as the rows in the matrix including space points and the fact that any basis of the subspace can be regarded as projective reconstruction. The projective reconstruction and the depth factors are obtained based on linear iteration.
摘要该文提出了一种基于子空间线性迭代的射影重建方法,该方法利用所有的图像序列构成的行向量生成的线性子空间之和与射影重建结构点构成的行向量生成的子空间是同一线性子空间及在该子空间中任何一个基底都可以作为射影重建的特性,线性迭代地求取射影重建及图像深度因子。

Based on the array signal processing and the eigenstructure decomposition method, the signal subspace and the noise subspace are achieved by reconstructing and decomposing the data matrix collected by the array sensors. By using the orthogonal properties of the two subspaces, the information about the velocities and bearings of spatial moving targets can be exactly obtained.

Firstly, urban space's development course and actuality of space's patterns are reviewed contrastly in the paper abroad and home. Then, existing problems of urban space at present in our country are discussed stressly:"Ten Faulty Expressions in Writing" of urban construction;"the Movement of Beautifying City" in china; the problem of urban characteristic; the problem of reforming of old city; the problem of residential segregation. The above problems' formed reasons and countermeasures are put forward. Then, the example of Xi'an and its existing problems of urban space and several countermeasures are analyzed in the paper. The transformation of three sections realized in the planning thought of urban space is put forward: from "elitism" to "plebeianism"; from mega-urban project design to "daily living space" and from "technology first" to "human-oriented".
论文首先从中西方城市空间形态的演变历程入手,对比分析了国内外的空间形态现状,重点论述了当前我国存在的城市空间问题:城市建设"十大败笔";中国"城市美化"运动;城市特色问题;旧城改造问题以及空间分异问题,分析了其形成原因并得出了解决途径,然后对西安进行了实例分析,总结出其城市空间存在问题并提出几点对策,接下来提出了城市空间规划理念应实现的三个方向的转变:从"精英主义"向"平民主义"理念转变、从大尺度城市设计向"日常生活空间"营造转变以及从"技术至上"向"以人为本"理念转变。

And Fewer fixations were required to find the target in the repeated configurations than in the new configurations. Furthermore, the distance of the first saccade from the target were smaller for the repeated than for the new displays. In addition, the probabilities of initial fixation landed on the target were greater for the repeated than for the new contexts.

Recently,atoms with higher order vanishing moment were defined by Krant-z etc on some particular spaces of homogeneous type,but it hasn't been solvedthoroughly on usual spaces of homogeneous type.On the other hand,krantz'sstudy was made under the condition which the measure of the sets constructedby single element is zero,therefore their work didn't include the case of integ-er Z as a particular space of homogeneous type.Indeed,as a Hardy space on Z,〓(0<p≤1)has been studied by some scholars.
尽管近来Krantz等人在某些齐型空间上定义了带高阶消失矩的原子,但在一般的齐型空间上建立带高阶消失矩的原子Hardy空间还没有完全解决,而且Krantz等人的工作是在单点集测度为零的条件下讨论的,因而不包括作为齐型空间的整数Z的情形。Z作为一类特殊的齐型空间,其上Hardy空间〓的问题有不少学者讨论过。
