LiveWire ImageJ Plugin

Most of the documentation for the plugins may be found in the thesis that was developed along with them. It might be downlaoded here.

In order to make the graduation thesis fully repeatable, I'm making the IVUS plugin available. This ImageJ plugin adds the functionality to slice an image frame sequence in 4 directions, so that longitudinal segmentation may be applied. It is used for Coronary Intravascular ultrasound images.
The download is available here http://sourceforge.net/project/showfiles.php?group_id=171446&package_id=195893&release_id=475672 under the ivussnakes package in IVUS Plugin release.
Enjoy it!

Abstract

This graduation thesis deals with intravascular ultrasound (IVUS) image segmentation through LiveWire and Snakes algorithms. As the type of ultrasound studied is the one from coronaries, there’s an initial detailing of the medical environment in which the problem is inserted.
The introduction is followed by an explanation of how LiveWire technique works, which is by calculating the shortest cost path between two pixels of the image. There’s a discussion about the implementation, using binary trees and a heap data structure. This is followed by the evaluation of which costs should be adopted, which were: modulus and

NEW FEATURES - Release 0.9.5

***Make sure you have ImageJ 1.37r or later and Java 1.5 ***

Works with color:
Now LiveWire is able to segment color images. This is done converting them to grayscale and then using the standard procedure (Thanks, Volker Bäcker!)

Run with macro: one can now use the following macro to use LiveWire
run ("LiveWire", "x0=50 y0=30 x1=95 y1=95 magnitude=43 direction=13 exponential=30 power=10");

Just go to Plugins->Macro->Record...
Then type the above macro, give it a name and press the "Create" button.
Now save the file and go to Plugins->Macro->Install... Then, choose the macro file you've just created.

New Features

Parameter configuration panel: the user can control the weight of the magnitude and gradient features.
Better user interface: the user is now able to see the anchor points, as well as move them around. Only one click is now enough to keep the segmentation and right click finishes it.
Source code is also embedded in a .jar file.

For the documentation, check the README.txt that comes along with the .jar file, as well as all the code, which is very comented.

There is also documentation in the thesis that was developed along with it. The thesis might be found here.
