In this paper, we propose a fast centerline extraction method to be used for gradient and
direction vector flow of active contours. The gradient and direction vector flow is a recently …

Aiming at the defects that the existing methods based on Parametric Active Contour Models
(PACM) cannot accurately locate to corners, and discontinuous edges were easily affected …

By incorporating the image gradient directional information into the geodesic active contour
model, we propose a novel active contour model called directional geodesic active contour …

Active contour models are widely used in image segmentation. In order to obtain ideal object
boundary, researchers utilize various information to define new models for image …

A new minimal path active contour model for boundary extraction is presented.
Implementing the new approach requires four steps (1) users place some initial end points …

In this paper, we propose a novel active contour method for image segmentation using a
local regional information on extendable search line. We call it the LRES active contour. Our …

The paper presents a new external force field for active contour model, which is called CGVF
(Curvature Gradient Vector Flow). CGVF improves on classical GVF by simplifying the …

There was considerable success in converting images into something like line drawings
without resorting to any but the most general prior knowledge about smoothness and …

In recent years, the field of active contour-based image segmentation has seen the
emergence of two competing approaches: Boundary-based and region-based approaches …

Active contour is a well-known image segmentation technique, commonly used to find object
boundaries in images. Its main benefit is its ability to retrieve an ordered collection of points …
