The geometry of a space curve is described in terms of a Euclidean invariant frame field, metric, connection, torsion and curvature. Here the torsion and curvature of the connection quantify the curve geometry. In order to retain a stable and reproducible description of that geometry, such that it is slightly affected by non-uniform protrusions of the curve, a linearised Euclidean shortening flow is proposed. (Semi)-discretised versions of the flow subsequently physically realise a concise and… 
The evolution of space curves by curvature and torsion
We apply Lie group based similarity methods to the study of a new, and widely relevant, class of objects, namely motions of a space curve. In particular, we consider the motion of a curve evolving
A Dynamic Scale–Space Paradigm
TLDR
A novel mathematical, physical and logical framework for describing an input image of the dynamics of physical fields, in particular the optic field dynamics, based on an exchange principle for a free energy of the physical field dynamics (represented through the equivalences) that in turn is linked to a statistical partition function.
Automatic tailoring and cloth modelling for animation characters
TLDR
This thesis considers the cloth fitting process as an optimization procedure which optimizes both the shape and size of each cloth pattern automatically, the integrity, design and size are evaluated in order to create 3D cloth for any character with different body shapes and proportions while preserve the original cloth design.
Magnetic resonance cholangiopancreatography image enhancement for automatic disease detection.
TLDR
Tests show promising results for some techniques, but not others, as viable image enhancement modules for automatic CAD systems for biliary and liver diseases.

The normalized curve shortening flow and homothetic solutions
The curve shortening problem, by now widely known, is to understand the evolution of regular closed curves γ: R/Z -> M moving according to the curvature normal vector: dy/dt = kN = -"the ZΛgradient
Differential and Integral Geometry of Linear Scale-Spaces
TLDR
This paper shows that geometry comes about by constructing connections on the basis of the similarity jets of the linear scale-spaces and by deriving related systems of Cartan structure equations.
Flow of nonconvex hypersurfaces into spheres
The flow of surfaces by functions of their principal curvatures has been intensively studied. It started with the work of Brakke [1], who used the formalism of geometric measure theory; a more

In this paper, we present a general study of the kinematics of deformable non-singular manifolds with codimension 1 evolving according to a first-order dynamics within a d- dimensional space, in
Shapes, shocks, and deformations I: The components of two-dimensional shape and the reaction-diffusion space
TLDR
The principles are organized around two basic intuitions: first, if a boundary were changed only slightly, then, in general, its shape would change only slightly; and second, that not all contours are shapes, but rather only those that can enclose “physical” material.

TLDR
The authors address the problem of representing the shape of three-dimensional or space curves by evaluating a number of shape representation methods that operate on two-dimensional objects and can be extended to apply to space curves.
Dynamic shape
TLDR
Relations with existing theories in vogue in robotics and AI, as well as in psychophysics are discussed, and it is argued that such relations find a logical place only in shape theories that involve morphogenesis.
Area and Length Preserving Geometric Invariant Scale-Spaces
In this paper, area preserving multi-scale representations of planar curves are described. This allows smoothing without shrinkage at the same time preserving all the scale-space properties. The
