Hello Matlab experts,
I want to fill up the gaps or open spaces in the the brown layer(skin). What would be the best way to do so?
Morophological operations like dilation is not feasible as it takes spaces from other voxels like yellow layer(bones).
I have shared the file in nifti format here: google drive link which can be read as
lab = niftiread('lab_superior.nii.gz');
Thanks.

HEre is a start:
h = strel('disk',5);
I1 = imdilate(yellow,h); % imdilate yellow part (bone)
I2 = I1 & ~yellow; % select outside region/area only
I = I2 & skin;

What about this?
I0 = imread('im.png');
I1 = ~im2bw(I0);
I2 = I1*0;
for j = 1:size(I1,2)
i = find(I1(:,j),1,'first');
if ~isempty(i)
I2(i,j) = true;
end
end
imshowpair(I1,I2,'montage')
