Contour Retrieval and Matching by Affine Invariant Fourier Descriptors
In the image plane, a 3 Dimensional movement of planar rigid object can be represented satisfactory by an affine motion of his boundary (the exterior contour) which we assume to b...

Projective Estimators for Point/Tangent Representations of Planar Curves
Recognizing shapes in multiview imaging is still a challenging task, which usually relies on geometrical invariants estimations. However, very few geometric estimators that are pro...

Dual evolution of planar parametric spline curves and T-spline level sets
By simultaneously considering evolution processes for parametric spline curves and implicitly defined curves, we formulate the framework of dual evolution. This allows us to combin...

Shape Analysis of Elastic Curves in Euclidean Spaces
—This paper introduces a square-root velocity (SRV) representation for analyzing shapes of curves in Euclidean spaces under an elastic metric. Due to this SRV representation the ...

Extracting geometric models from medieval moulding profiles for case-based reasoning
Cross-sectional pmfiles of medieval mouldings are often considered to be a vital form of data to Art Historians. Mouldings were often used to highlight salient areas of buildings,...
