Deformable Velcro surfaces

Proceedings of IEEE International Conference on Computer Vision, 2002
We present a new approach to segmentation of 3-D shapes that initializes and then optimizes a 3-D surface model given only the data and a very small number of 3-D seed points and corresponding surface normals. This is a valuable capability for medical, robotic and cartographic applications where such seed points can be naturally supplied.

DEFORMATIONS OF INSTANTON SURFACES

Mathematics of the USSR-Izvestiya, 1992
Summary: A solution is given for the problem of determining smoothness invariants on an algebraic surface from a nonsmooth compact moduli space of instantons. For this a study is made of the deformation of the instanton surface. The results are used to distinguish smoothness on certain algebraic surfaces.

Omnidirectional displacements for deformable surfaces

Medical Image Analysis, 2013
Deformable surface models are often represented as triangular meshes in image segmentation applications. For a fast and easily regularized deformation onto the target object boundary, the vertices of the mesh are commonly moved along line segments (typically surface normals).

Surface deformations in Central Asia

Tectonophysics, 1986
Abstract Measurement of surface deformations caused by drift of the Indian tectonic plate against the Eurasian plate has been performed with short-range EDM-instruments in U.S.S.R. Central Asia. A relative motion of 1.5 cm/yr has been found. It has been shown that uncertainty in the refraction model used in derivation of the motion vectors plays a ...

Three-Dimensional Tire Deformation on Deformable Surfaces

Transactions of the ASAE, 1987
ABSTRACTAsystem was devised to measure three-dimensional deformation of a pneumatic tractor tire at three positions across the tread width on both lug and undertread surfaces. Tire deformations were compared to measured radial and tangential stresses at the soil-tire contact surface.

Jamming on convex deformable surfaces

Soft Matter
We propose a new scenario, metric jamming, where particles rigidify on a deformable surface. The resulting states possess mechanical properties tunable between classically jammed and conventional elastic media and new types of mode that couple particle and shape degrees of freedom.

Surface Deformation Measurements

2003
Accurate surface deformation measurements are often required in industrial manufacturing processes to ensure the quality of products and for monitoring the structural health of components subjected to mechanical loads. Surface deformation can be measured at discrete points on a specimen by using contacting instruments such as dial gauges, styluses, or ...

Deformable Surface Tracking Ambiguities

2007 IEEE Conference on Computer Vision and Pattern Recognition, 2007
We study from a theoretical standpoint the ambiguities that occur when tracking a generic deformable surface under monocular perspective projection given 3D to 2D correspondences. We show that, additionally to the known scale ambiguity, a set of potential ambiguities can be clearly identified.
