The elastic constant of the spring model will decreases as the process proceeds.

引 言图象的变形匹配是指对于一幅图象通过寻求一种空间变换模型来使它经过变换后与另一幅图象的空间相关性达到最大[1] 的过程。

In view of the demand of computerized eye-glasses-wearing system, an approach to match two dimensional (2D) human head images with 3D glasses frame graphics in 3D space has been proposed. First, the operator points out three or six key points, which are used to locate 3D eye-glasses frame, on the human face image displayed on the computer screen interactively.

论文针对计算机化眼镜配戴系统的要求，提出了一种在三维空间匹配二维人头图象和三维眼镜图形的方法，即通过人机交互方法，由操作者在显示于计算机屏幕上的二维人头图象上，指出确定三维眼镜位置的三个或六个关键点的二维坐标及其三维对应点，从而可以近似求出人面朝向及视点坐标，再用相应位置上的三维通用人头图形替换二维人面图象，计算人面和眼镜间的遮挡关系并显示，从而完成二者的空间匹配。

Based on the histogram multifractal spectrum estimation, a kernel density estimation of multifractal spectrum is suggested, and moreover a edge dection method by multifractal spectrum is present, simulation results show that image edges detecting through this method have good global and local character, and are more finner.

The hierarchical structure of the retrieval strategy is analyzed to reach the real-time and retrieval accuracy requirement. A trademark image database system under hierarchical scheme is implemented: the string-matching method is first used to reduce the image search scope under man-machine interaction, then smallest enclosed rectangle and Hausdorff distance metric are used to measure the similarity between trademarks under image region normalization and transform invariance.

Based on the traits of dyadic wavelet decomposition of signal and that of the distribution of wavelet image coefficients, PLVQ and ZR are conjoined by making use of D\-4 lattice. Firstly, Pyramidal lattice vector quantization is adopted to quantize wavelet image coefficients. Nonzero lattice vectors and zero lattice vectors are formed. Secondly, nonzero lattice vectors are dealt with by adopting complex entropy coding. Finally, in order to fix on the position of nonzero lattice vector effectively, that is, to deal with zero lattice vectors effectively, the concept of significant map is introduced into. The significant map is scanned two times from down to up and from up to down.

If we knew in advance the image on the page is placed, then use the protractor and the original bottom edge of the platform placed in the drum of peace into a precise point of the original manuscript, which will be the highest quality images, and do not have image processing software further rotation.

如果我们事先就知道图象在页面上是如何放置的，那么使用量角器和原稿底边在滚筒和平台上放置原稿成精确的角度，会得到最高质量的图象，而不必在图象处理软件中再作旋转。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
