Proposed a representation scheme for 3D face -- Surface UnfoldingFor its irregular sampling in 3D space, 3D face surface cannot be processed by many orthogonal and subspace analysis toolkits directly, i.e. DFT, DCT, PCA, LCA. Surface Unfolding projects the 3D face to a 2D plane while retaining its intrinsic geometry properties of angle and area which issues a surface representation — Unfolded Image.

At first, some properties in the sampling subspace are classified. Then, that the subspace spanned by the translation of a function is also a subspace is proved in the shift invariant subspace.

首先通过Zak变换刻画了抽样空间的一些性质，然后证明了在一个平移不变的抽样空间中，由其中任一个函数的整平移所张成的子空间也是抽样空间。

On the base of analyzing the structural characteristic of 8098 single chip Microcomputer, a multi-dimension signal processing system with simple structure and powerful function is developed using 8098, which not only function as signal sampling and processing, but also the calculation of inverse 6×6 matrix.

对8098单片机的结构性能进行了分析研究，并应用8098单片机研制成功一套多维信号处理系统。

This paper proposes a novel interpolator that is the All Phase Inverse Discrete Cosine Sequency Filter. Based on the theory of the All Phase, the APIDCSF considers the surrounding samples'influence on the center one throughly, and takes the average of IDCT orthogonal filtering of surrounding sampling blocks which include the center sample as its orthogonal transformed value.

在全相位理论的基础上，充分考虑了周围邻域对中心样本的影响，以包含该中心样本的所有邻域正交变换滤波的均值作为其正交变换滤波值，构造了全相位离散反余弦列率滤波器组(All Phase Inverse Discrete Cosine Sequency Filter， APIDCSF)，其内插性能好于高阶消失矩的环形Neville滤波器。
