First, each shape is represented by the eigenvectors of an appropriately defined affinity matrix based on approximated geodesic distance, forming a spectral embedding which achieves normalization against rigid-body transformations, uniform scaling, and shape articulation (i.e., pose changing). This procedure is called the pose-oblivious transform.
首先,针对每一个形状都基于谱嵌入的方法求得其相应的谱嵌入表示,这里的谱嵌入是基于以近似测地距离为基础构造出的仿射矩阵的特征向量得到的,这一过程称为姿态无关变换,经过这一变换,模型的形状的描述符就具备了刚体变换不变、均匀缩放不变和姿态无关的特性。

The main results of the investigation are as following:(1) Some important criteria for the design of multi-layer structure are acquired: the ratio of the layer thickness to the contact diameter should be controlled to a value about 0.8; increasing the number of the gradient layers and elasticity modulus of the top layer would benefit to the yield strength and the stress status at the interface.(2)By means of molecular dynamics simulations for a indentation and sliding process, it is discovered that dislocations of 45 direction to the surface occur in the surfaces layer, which is correspond to the direction of the plastic flows observed in the macroscopic continuous medium. The irreversible deformation caused by the dislocation and the atom piles at the surface are responsible for the irreversibility of the force response. They are also the main factors for the friction generation. The temperature and the indentation velocity have significant effects on the deformation behaviors of the material of the surface layer. The yield strength would increase obviously if the indentation velocity is greater than 10 m/s.(3)A method to evaluate the fracture toughness of coating by estimating the crack-density functionβof a Wicker''s indentation was proposed. Meanwhile a new surface treatment technology was developed using non-equilibrium plasma.(4)A MD-FE hybrid method and corresponding software was developed to analysis the tribological behaviors for multiplayer system.

The method first embeds watermark into the geometric invariant Fourier-Mellin domain of an image to weaken the geometric distortion, brought by printing process, of the watermark in presswork, and the image is then used to create presswork via a legal printing process. Secondly, the method rectifies rescanned image from the presswork by using Radon transformation and the embedded watermark in it is detected. Since there is an obvious difference between the destruction degrees of the watermark caused respectively by legal and pirated printing process, we can judge whether a copy of presswork is valid or not just by computing the ratio of the successfully derived watermark and comparing it with a predefined threshold.
该方法先将水印嵌入到具有几何不变性的Fourier-Mellin域中,以削弱正版印刷过程中的几何失真对水印的破坏;再利用Radon变换对由扫描印刷品所获得的图像进行矫正,并从图像中提取嵌入的水印信息;由于正版和盗版印刷过程对水印的破坏程度区别明显,该方法最终通过计算水印提取的正确率来度量这种破坏,并将其与预先制定的阈值进行比较来判定印刷品的正伪。
