A localised elastic net technique for lung boundary extraction from magnetic resonance images

Fifth International Conference on Artificial Neural Networks, 1997
This paper is concerned with the key process of segmentation of the input image and/or extraction of desired features. In computer vision systems, with particular application to segmenting the human lung boundaries from magnetic resonance images of human torsos.

Evaluation Of An Elastic Curve Technique For Finding The Auroral Oval From Satellite Images Automatically

IEEE Transactions on Geoscience and Remote Sensing, 1990
An automated algorithm for finding the inner boundary based on recently proposed computer vision technique is described. The algorithm is analogous to solving the equations of motion for an elastic curve, where the forces are provided by the image. The resulting equilibrium position of the elastic curve provides an automated method for finding the ...

Imaging Hydrothermal Circulation Paths along the East Pacific Rise Using Elastic Wave-equation Based Inversion Technique

78th EAGE Conference and Exhibition 2016, 2016
Summary Along mid-ocean ridges, locations where hydrothermal fluids emerge onto the seafloor and potentially significant mineral ore bodies form, have been considered for future mineral exploitation. However, before the mining takes place at hydrothermal vents we need to better understand circulation paths of the fluids that are the main transporters ...

Probabilistic Characterization of Elastic Properties of Composites Using Digital Image Correlation Technique

Reliability assessment of composite structures requires probabilistic description of material properties including high-fidelity evaluation of their main statistical parameters. With respect to composite materials, the probabilistic description should capture anisotropy of random elastic properties and their possible statistical correlations. A general

A composite imaging technique for high frame-rate and full-view cardiovascular ultrasound and elasticity imaging

2012
The frame-rate of ultrasound radio-frequency (RF) data acquisition is critical for imaging of the pulse wave and electromechanical wave propagation in cardiovascular tissues as well as improving the strain estimation. Therefore, an automated method had been developed to overcome the frame-rate limitations on standard systems by retrospective multi ...
