Integrated Active Contours for Texture Segmentation
Active contours without edges anisotropic diffusion Beltrami framework Gabor analysis geodesic active contours image manifolds texture segmentation
2010/1/7
We address the issue of textured image segmentation in the context of the Gabor feature space of images. Gabor filters tuned to a set of orientations, scales and frequencies are applied to
the images...
Geodesic Active Contours Applied to Texture Feature Space
Geodesic Active Contours Texture Feature Space segmentation
2010/1/7
Gabor Analysis is frequently used for texture analysis and segmentation. Once the Gaborian feature space is generated it may be interpreted in various ways for image analysis and segmentation. Image s...

3D Brain Segmentation Interaction
2009/9/8
Important attributes of 3D brain cortex segmentation algorithms include robustness, accuracy, computational efficiency, and facilitation of user interaction, yet few algorithms incorporate all of thes...
Anisotropic Elastography for Local Passive Properties and Active Contractility of Myocardium from Dynamic Heart Imaging Sequence
Myocardium Dynamic Heart Imaging Sequence
2009/9/8
Major heart diseases such as ischemia and hypertrophic myocardiopathy are accompanied with significant changes in the passive mechanical properties and active contractility of myocardium. Identificati...
A Context-Sensitive Active Contour for 2D Corpus Callosum Segmentation
Context-Sensitive 2D Corpus Callosum Segmentation
2009/9/4
We propose a new context-sensitive active contour for 2D corpus callosum segmentation. After a seed contour consisting of interconnected parts is being initialized by the user, each part will start to...
Segmentation of Myocardial Boundaries in Tagged Cardiac MRI Using Active Contours: A Gradient-Based Approach Integrating Texture Analysis
Myocardial Boundaries MRI
2009/9/4
The noninvasive assessment of cardiac function is of first importance for the diagnosis of cardiovascular diseases. Among all medical scanners only a few enables radiologists to evaluate the local car...
Development of a New Method for Discriminating Embolus from Air Bubble by Active Ultrasound Doppler Method. 1 (Experiments of Ultrasound Irradiation Perpendicular to a Tube Axis in Flows of Water and Modeled Blood)
USD TCD cerebral embolism characteristic acoustic impedance acoustic radiation force
2009/8/24
An “active” ultrasound Doppler method was newly developed in order to directly and easily discriminate emboli from micro bubbles flowing in blood vessel. The principle of this method is based on measu...
