Interactive Liver Tumor Segmentation Using Graph-cuts and Watershed
starstarstarstarstar
We present in this paper an application of minimal surfaces and Markov random fields to the segmentation of liver tumors. The originality of the work consists in applying these models to the region adjacency graph of a watershed transform. We detail [...]

Segmentation of Carotid Arteries By Graph-Cuts Using Centerline Models
No opinion
In this paper, we present a semi-automtic method for segmenting carotid arteries in contrast enhanced (CE)-CT angiography (CTA) scans. The segmentation algorithm extracts the lumen of carotid arteries between user specfied locations. Specifically, the [...]

Graph Cuts, <i>Caveat Utilitor</i>, and Euler's Bridges of Konigsberg
starstarstarstarstar
Graph-based algorithms have enjoyed renewed interest for solving computer vision problems. These algorithms have been the subject of intense interest and research. In order to maintain the ITK library au courant, we developed a framework for graph-based [...]

Interactive Image Graph Cut Segmentation
No opinion
This document presents a system to "scribble" on an image to mark foreground and background pixels and then feed these pixels to a graph cuts segmentation technique. The interaction is done using the Visualization Toolkit and the processing is done using the [...]

Deformable Registration with Discontinuity Preservation using Multi-Scale MRF
No opinion
Deformable (2D or 3D) medical image registration is a challenging problem. Existing approaches assume that the underlying deformation is smooth. This smoothness assumption allows for solving the deformable registration at a coarse resolution and interpolate [...]

Automatized Evaluation of the Left Ventricular Ejection Fraction from Echocardiographic Images Using Graph Cut
No opinion
In this paper, we present a fast and interactive graph cut method for 3D segmentation of the endocardial wall of the left ventricle (LV) given 3D echocardiographic images. This is a challenging task due to the poor contrast and the low signal-to-noise ratio [...]
