variational model

UV mapping is a classical problem in computer graphics aiming at computing a planar parameterization of the input mesh with the lowest …

We propose a graph cut model to optimize bidimensional shapes with respect to the elastica energy. At each iteration our model selects …

Geometric priors have been shown to be useful in image segmentation to regularize results. For example, the classical Mumford-Shah …

Digital objects and digital surfaces are isothetic structures per se. Such surfaces are thus not adapted to direct visualization with …

We propose an original method for vectorizing an image or zooming it at an arbitrary scale. The core of our method relies on the …

The Mumford-Shah functional approximates a function by a piecewise smooth function. Its versatility makes it ideal for tasks such as …

Voxel based modeling is an attractive way to represent complex multi-material objects. Multi-labeled voxel models are also ubiquitous …
