FRACTIONAL DIFFERENTIATION-BASED EDGE ENERGY DRIVEN ACTIVE CONTOURS FOR ROBUST IMAGE SEGMENTATION
In this paper, a new fractional differentiation-based active contour model for robust image segmentation is presented. A new edge energy is introduced, in which the contour evolution is driven by the difference between the fractional derivatives directed

In the traditional active contour models, global region‐based methods fail to segment images with intensity inhomogeneity, and local region‐based methods are sensitive to initial contour.

A hybrid level set model for image segmentation.
Active contour models driven by local binary fitting energy can segment images with inhomogeneous intensity, while being prone to falling into a local minima. However, the segmentation result largely depends on the location of the initial contour.

Automated Optic Disc Segmentation Using Basis Splines-Based Active Contour
We develop a fully automated method for the segmentation of optic disc in retinal fundus images using basis-spline-based active contour. The segmentation is achieved by performing scaling, translation, and rotation of the active contour, thereby giving ...

A Hybrid Active Contour Segmentation Method for Myocardial D-SPECT Images
The ischaemic heart disease has become one of the leading causes of mortality worldwide. Dynamic single-photon emission computed tomography (D-SPECT) is an advanced routine diagnostic tool commonly used to validate the myocardial function in patients ...

Ontology-Coupled Active Contours for Dynamic Video Scene Understanding [PDF]
In this paper, we present an innovative approach coupling active contours with an ontological representation of knowledge, in order to understand scenes acquired by a moving camera and containing multiple non-rigid objects evolving over space and time ...

This paper presents a method for synthetic aperture radar (SAR) image segmentation by draing upon a reaction–diffusion (RD) level set evolution (LSE) equation. The well-known RD theory consists of two main parts: reaction and diffusion terms.

Medical image segmentation using modified active contour method [PDF]
Image data is of major practical importance in medical informatics. Accurate segmentation of medical images largely determines the final result of image analysis, which provides significant information for 3D visualization, surgical planning and

We propose a method for interactive boundary extraction which combines a deep, patch-based representation with an active contour framework. We train a class-specific convolutional neural network which predicts a vector pointing from the respective point on the evolving contour towards the closest point on the boundary of the object of interest.
