This paper presents extensions which improve the performance of the shape-based
deformable active contour model presented earlier in [IEEE Conf. Comput. Vision Pattern …

We propose a new model for active contours to detect objects in a given image, based on
techniques of curve evolution, Mumford-Shah (1989) functional for segmentation and level …

The first step for human face recognition is to locate the head boundary in a head-and-
shoulders image. An approach that uses adaptive contour models or" snakes" is described …

Snakes, or active contours, are used extensively in computer vision and image processing
applications, particularly to locate object boundaries. Problems associated with initialization …

Multi-resolution methods applied to active contour models can speed up processes and
improve results. In order to estimate those improvements, we describe and compare in this …

A comparative study to review eight different deformable contour methods (DCMs) of snakes
and level set methods applied to the medical image segmentation is presented. These …

We consider the problem of segmenting an image through the minimization of an energy
criterion involving region and boundary functionals. We show that one can go from one class …

Shape modeling is an important constituent of computer vision as well as computer graphics
research. Shape models aid the tasks of object representation and recognition. This paper …
