平移的

This is my last OpenGL for a project to use the "three-dimensional vector space / point" and related functions, they can use a definition of space vector / points, for the vector translation, zooming and rotation, the use of correlation function can also achieve two vector by the fork, get a Vectors absolute length of a vector unit, received a 3:00 decision vector perpendicular to the plane, a space to be the distance between two points, two vector to be the plot points, to be the angle between two vectors, such as operating for the use of user-friendly, each function is detailed Notes, it is particularly important if the calculation vector plot points, fork also took note, we hope to have useful.

这是我过去进行一个OpenGL项目时使用到的"三维空间向量/点"类及相关函数，使用它们可以定义一个空间向量/点，实现向量的平移，缩放和旋转等，使用相关函数还可以实现两向量的叉乘，得到一个向量的绝对长度，将一个向量单位化，得到一个三点决定的平面的垂直向量，得到空间中两点的距离，得到两向量的点积，得到两向量的夹角等操作，为方便用户的使用，每个函数都有详细的注释，特别重要的向量计算如点积，叉乘还有相关说明，希望对大家有所用处。

Although these injuries may consist of a variety of posterior element pathologies spanning the spectrum from fracture separation of the lateral mass 25,26 (with translation or rotation since an undisplaced lateral mass fracture falls within the compression morphology) through completely dislocated or locked facets.

尽管这种损伤可以包含多种后方结构的病理改变，包括从侧块的骨折分离到完全的脱位或关节交锁，各种程度的棘突、椎板、侧块等后方结构的骨折伴随椎体的爆裂、矢状面和/或冠状面的骨折，如所谓的泪滴状骨折。所有这些损伤存在于1个椎体相对于邻近椎体的平移。

The characteristics of image moments can be applied in manyfields. We apply Tebechbief moment characteristic to match replace of using graycharacteristic as primitives. An area moment has the property of unsensitive to transition,rotation and sealed change of area, the property of area moment is applied in the areamatching approach in our thesis, combined with a new constraint, and a novel area-basedmatching approach is proposed.

Furthermore,the adsorption of acetylene on the Ni(111)surface is investigatedby DV-Xα method,as well as its migration pathway from the aligned bridgesite,the favorite adsorption site for ethylene,to the cross-bridge site.Afterstudying several reaction pathways of C2H2 on Ni(111),we find that acetylene,as the product of dehydrogenated ethylene,will migrate from the alignedbridge site to the cross-bridge site with a very small energy barrier,0.02eV.

However, to construct a tensor product orthonomal wavelet basis in L〓, 2〓-1 different functions are used. Furthermore, it is concluded that the family, obtained by dilations and translations from this radial wavelet as well as their linear combinations, can constitute an orthonomal basis in L〓. The conclusion is a major breakthrough in multidimensional wavelet analysis.

A large number of relaxation schemes for feature mapping, claimed to be invariant to transformation, have been reported. However, most of them can deal with transfor-mations involving only rotation and translation, but not scaling. To stay away from the issue of scaling, unrealistic assumptions have to be imposed, such as the conjectures that range data are available so that objects can be rescaled before mapping, and that object shapes are complete so that ratios between object shapes and prototypes can be figured out beforehand. In this paper, we propose a relaxation scheme which is able to be in-variant at a time to rotation, translation, as well as scaling.

截至目前为止已有不少供几何特徵匹配用之松弛法架构被提出来，这些架构虽然宣称可以对空间转移具有不变性，但是实际上，大部分只能处理和旋转及平移有关的转移，对於具有尺度因素的转换泽尽量避免，因此，便有各种不同的假设被加诸於所考虑的问题，例如假设我们已知景深值，因此可以先将物件的尺度正规化后再比对，或者假设物形式晚整的，於是物形和模型间的尺度比率事先可以推知。

Experimental results on the Olivetti Research Laboratory face database show that performing energy-normalization and the Fourier transform in preprocessing stage is feasible; better than the traditional eigenspace method, the local eigenspectra-based scheme gets higher recognition rate; comparing with the Euclidean distance rule, the Parzen classifier is more powerful for face recognition.
