只有物体的位置(平移变换)和朝向(旋转变换)发生改变，而形状不变，得到的变换称为刚性变换。非刚性变换就是比这更复杂的变换，如伸缩，仿射，透射，多项式等一些比较复杂的变换。例如ps中自由变换命令里面的斜切、扭曲、透视这些功能就属于非刚性变换 ...
It is found that the dominant mechanism of material removal of precision grinding for nWC/12Co coatings is mainly the inelastic deformation including plastic deformation with a certain amount of pulverization, and less removal from material britt. 结果表明:在大多数磨 削条件下,nWC/12Co磨削的材料去...

再看SIFT算法原文时看到non-rigid deformation，知网翻译成非刚性变换。图像处理中刚性变换和非刚性变换是...
In this work paper, a non-rigid deformation pipeline is proposed for brain shift compensation of preoperative imaging datasets using superficial blood vessels as landmarks. The input was preoperative and intraoperative 3D image sets of superficial vessel centerlines. The intraoperative vessels (obtained...
In this paper, we present a non-rigid surface registration approach to MR-TRUS fusion based on a statistical deformation model (SDM) of intra-procedural deformations derived from clinical training data. Synthetic validation experiments quantifying registration volume of interest overlaps of the PI-RADS...
There are two main problems in the registration of serial section images: (1) non-rigid deformation occurs during the sectioning process; and (2) problems in the registration of a large number of sections, consist of tissue discontinuity caused by registration failure and an accumulation of scale...
deformation graph的使用: 上文说到关键帧要通过变形在空间上与其他帧吻合,无法为每个顶点分配旋转矩阵R+平移向量T(运算量大,自由度高,无法约束),实际做法是生成少量 nodes, 每个node分配R+T,通过nodes 的变形支配关键帧顶点的运动,求解的是nodes 的R+T,就和人体的关节类似。

We proposed a free-form deformation method with a ruled surface and an assembly method to align the deformable components mutually. The method employs a bottom-up approach that does not require reference data for target objects. The proposed framework narrows down the searching space for ...
