MAC: Magnetostatic Active Contour Model

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2008
We propose an active contour model using an external force field that is based on magnetostatics and hypothesized magnetic interactions between the active contour and object boundaries. The major contribution of the method is that the interaction of its forces can greatly improve the active contour in capturing complex geometries and dealing with ...

Fuzzy active contour model

open access: yesIEE Proceedings - Vision, Image, and Signal Processing, 2000
A new method for representing and tracking of object boundaries is presented, which allows for the integration of uncertain a priori knowledge into an active contour model. The novel concept of fuzzy snakes is developed to allow for an intuitive specification of the properties of an object's boundary.

Active contour model by combining edge and region information discrete dynamic systems

open access: yesAdvances in Mechanical Engineering, 2017
The basic idea of active contour model upon the image segmentation problem is evolved into a closed curve about the functional minimization problems. Active contour model based on edge information takes advantage of gradient information, and it has some ...

ORACM: Online region-based active contour model

open access: yesExpert Systems With Applications, 2013
A new online region-based active contour model (ORACM) is proposed in this paper. The classical geodesic active contour (GAC) model has only local segmentation property, although the Chan-Vese (C-V) model possesses global.

An Improved Active Contour Model With Fuzzy Approach.

open access: yes, 1996
An active contour model has been widely applied to image segmentation and analysis. A contour model is able to be deformed to fit to an expected object based on an energy minimization. However, the conditions of initialising a contour model and defining internal energy parameters are important factors to the desired deformation.

Intracranial contour extraction with active contour models

Journal of Magnetic Resonance Imaging, 1997
AbstractA novel image processing scheme for extracting the intracranial contours in axial magnetic resonance data sets is proposed. The scheme incorporates the method of active contour models, a recently introduced paradigm for contour extraction. Its performance is nearly ideal for T2‐weighted images.

Fuzzy Active Contour Models

2011 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE 2011), 2011
This paper presents a Fuzzy Active Contour Model for image segmentation using three variations. The proposed models are based on the Fuzzy Energy-Based Active Contour model introduced by Krinidis and Chatzis. First, an update criteria that changes only localized membership values at each iteration is introduced.

Snakes: Active contour models

International Journal of Computer Vision, 1988
A snake is an energy-minimizing spline guided by external constraint forces and influenced by image forces that pull it toward features such as lines and edges. Snakes are active contour models: they lock onto nearby edges, localizing them accurately. Scale-space continuation can be used to enlarge the capture region surrounding a feature.
