旋转(rotation),沿着任意方向的旋转; 非刚体变换:描述的是对几何物体大小而非形状的改变。 也即: 刚体变换:shift or reflection(A rigid transformation preserves all distances and angle measures (and depending on your taste, orientation too),刚体变换能够继续保持物体中各点的距离和角度) 非刚体变换:stretching...

A nonrigid transformation describes any transformation of a geometrical object that changes the size, but not the shape.Stretching or dilating are examples of non-rigid types of transformation. A transformation describes any operation that is performed on a shape. Simple transformations, such as moving...

Non-rigid registration is challenging because it is ill-posed with high degrees of freedom and is thus sensitive to noise and outliers. We propose a robust non-rigid registration method using reweighted sparsities on position and transformation to estimate the deformations between 3-D shapes. We ...
Anisotropic multistability can be done using a stacked Miura-ori structure due to the nonlinear behavior between the rigid folding and the crease bending [136,137]. Such structure exhibit different mechanical equilibria along the principal axes of the unit cell, i.e., two force–displacement ...
One presents numerous approaches for the construction of variational principles for equations with operators which, in general, are nonpotential. One consi
A new accurate and robust non-rigid point set registration method, named DSMM, is proposed for non-rigid point set registration in the presence of significant amounts of missing correspondences and outliers. The key idea of this algorithm is to consider
After this relaxation, however, vortices retain stationary or rigid cores and consistently feature a uniform velocity. After the annihilation event, we can see traces of their diffusive cores in the excitations produced by the vortex annihilation, as seen by the quantum pressure in the system, ...
12). Thus, to identify the matching object, subjects had to be able to visualize not only the effects of rigid rotations, as in standard mental rotations experiments (Shepard & Metzler, 1971), but also the effects of non-rigid transformation. Failing that, to succeed at the task, they ...
