This paper deals with image and video segmentation using active contours. The proposed
variational approach is based on a criterion featuring a shape prior allowing free-form …

We present a new way of constraining the evolution of a region-based active contour with
respect to a reference shape. Minimizing a shape prior, defined as a distance between …

We present a new class of continuously defined parametric snakes using a special kind of
exponential splines as basis functions. We have enforced our bases to have the shortest …

This paper deals with fast image and video segmentation using active contours. Region-
based active contours using level sets are powerful techniques for video segmentation, but …

In this paper, we present a new way of constraining the evolution of an active contour with
respect to a set of fixed reference shapes. This approach is based on a description of …

Interactive video segmentation systems aim at producing sub-pixel-level object boundaries
for visual effect applications. Recent approaches mainly focus on using sparse user input (ie …

This paper deals with fast image and video segmentation using active contours. Region
based active contours using level-sets are powerful techniques for video segmentation hut …

Parametric active contours are an attractive approach for image segmentation, thanks to
their computational efficiency. They are driven by application-dependent energies that …

The likelihood for patterns of continuous features needed for probabilistic inference in a
Bayesian network classifier (BNC) may be computed by kernel density estimation (KDE) …

We propose a new parametric 3D snake with cylindrical topology. Its construction is based
on interpolatory basis functions which facilitates user-interaction because the control points …
