Region growing algorithm
no vote
Application background A recursive region growing algorithm for 2D and 3D grayscale image sets with polygon and binary mask output. The main purpose of this function lies on clean and highly documented code. Key Technology
Usage:
[P, J] = regionGrowing(cIM, initPos, thresVal, maxDist, tfMean, tfFillHoles, tfSimplify)
Inputs:
- cIM: 2D/3D grayscale matrix
- initPos: Coordinates for initial seed position
- thresVal: Absolute threshold level to be included
- maxDist: Maximum d

Horizontal set partition lung contour
no vote
Application background
This matlab code is used to segment the lung contour.
You can use a lung mask to get the contours of the whole series of lung CT.
Key Technology
The basic idea of this is from C-V model of Active Contour Model.
