On active contour models and balloons
CVGIP: Image Understanding, 1991Summary: The use of energy-minimizing curves, known as ``snakes'', to extract features of interest in images has been introduced by \textit{M. Kass}, \textit{A. Witkin} and \textit{D. Terzopoulos} [Int. J. Comput. Vision 1, 321-331 (1987)]. We present a model of deformation which solves some of the problems encountered with the original method.

A multistage, optimal active contour model
IEEE Transactions on Image Processing, 1996Energy-minimizing active contour models or snakes can be used in many applications such as edge detection, motion tracking, image matching, computer vision, and three-dimensional (3-D) reconstruction. We present a novel snake that is superior both in accuracy and convergence speed over previous snake algorithms.

Geometric models for active contours
Proceedings., International Conference on Image Processing, 2002A geometric formulation of active contours for 2D, 3D boundary detection and motion tracking is presented. The technique is based on active contours evolving in time according to intrinsic geometric measures of the image. The evolving contours naturally split and merge, allowing the simultaneous detection of several objects and both interior and ...

A Charged Geometric Model for Active Contours
18th International Conference on Pattern Recognition (ICPR'06), 2006This paper presents a new deformable model based on charged particle dynamics and geometric contour propagation. It detects object boundaries with a charged active contour that propagates under the influence of Lorentz forces in an image-based electrostatic field.

A novel, physical-based force, called as Lorentz force inspired by classical electrodynamics is introduced for the active contour models, and the truncation computing method of Lorentz Force is detailed. Several comparative results indicate that the new force field has similar effects with the Gradient Vector Flow (GVF) field, but it has a remarkable ...

An adaptive Geodesic Active Contour model
2010 Sixth International Conference on Natural Computation, 2010In order to solve the shortcoming of Geodesic Active Contour model that would possibly sink into the non-ideal local minimum when segmenting the objects having concave boundary, an adaptive Geodesic Active Contour model was presented. The new model could adjust the evolution speed of curve based on the curvature of curve and gradient of image by adding

Frequency-tuned active contour model
Neurocomputing, 2018Abstract Active contour model (ACM) is able to obtain sub-pixel precision segmentation and has been widely employed in biomedical image analysis and video segmentation. Existing region-based ACMs (RACM) without enough prior constraints, however, easily fail when segmenting low quality images, e.g.

Double Contour Active Shape Models
Procedings of the British Machine Vision Conference 2005, 2005Statistical shape models are often learned from examples based on landmark correspondences between annotated examples. A method is proposed for learning such models from contours with inconsistent bifurcations and loops. It is evaluated on the task of segmenting tibial contours in knee radiographs. Results are presented using various features, distance

Face contour tracking in video using active contour model
2004 International Conference on Image Processing, 2004. ICIP '04., 2005Face contour represents important information used for human face analysis in image and video. Here, we propose an improvement to the conventional active contour model, called Snake, to track complex face contour. We propose using gradient angular difference (GAD) to constrain the Snake contour to the specific face region.
