Automated lung segmentation

An automated lung segmentation uses profile matching and random walker algorithm

In the attached files, we have used profile matching and random walker algorithm to automatically segment posterior-anterior lung x-ray. The paper behind the technique is:

Digital Signal Processing 23(3), 1022-1031
.
Type 'TUBGUI_003' to launch the algorithm. We have provided two files as sample to demonstrate the segmentation: ‘PATIENT07.mat’ and ‘PATIENT08.mat’.
