REGIONGROWING A MEXed 2D/3D region growing algorithm.

lMASK = REGIONGROWING(dIMG, dMAXDIF, iSEED) Returns a binary mask lMASK, the result of growing a region from the seed point iSEED. The stoping critereon is fulfilled if no voxels in the region's 4-neighbourhood have an intensity difference smaller than dMAXDIF to the region's mean intensity.

If the seed point is not supplied, a GUI lets you select it. If no output is requested, the result of the region growing is visualized

IMPORTANT NOTE: This Matlab function is a front-end for a fast mex function. Compile it by making the directiory containing this file your current Matlab working directory and typing

mex RegionGrowing_mex.cpp

in the Matlab console.

Example (requires image processing toolbox)

load mri; % Gives variable D; RegionGrowing(squeeze(D), 10, [1 1 1]); % <- segments the background
