Creating binary 3D mask from MR volume

Hello All,
I am trying to create a 3D binary mask for MR head volume. The image has 0 intensity for background and the tissue inside the image has integers. Morphological operations provide me very noisy output.
This is after bwconncomp, thresholding and imerode options.
Are there better ways to get volumetric masks?

I don't think the noise on the mask is the issue. Why did your classification routine quit classifying stuff below that line other than the blue stuff? For some reason, you have a mask that just quits below that line, and that has nothing to do with little noisy blips on it.

Hello banikr,
I think this is what you want ... if I am not wrong.
load mri;
% load mriVolume; %3D MRI data with data variable name 'mriVolume'
mriVolume = D;
% Assuming background pixels are 0
bwMask = false(size(mriVolume));
pixIndex = find(mriVolume > 0);
bwMask(pixIndex) = 1;

@ banikr,
ok got it, if MRI data is possible to share, please share. love to work on it.
