Hi, I want to separate the lung tissue from the CT images taken from the chest, but the code I use removes the lung tumors or other parts of the lung itself, and I want the complete lung tissue. can you help me

z='D:\payanname\codes\lowerleg_imgs\';

d=dir(fullfile(z,'\*.bmp'));

nfiles = length(d);

for ii=1:nfiles

I = imread(strcat(z,d(ii).name));

BW = I > 40;

BW = imcomplement(BW);

BW = imclearborder(BW);

BW = imfill(BW, 'holes');

radius = 3;

decomposition = 0;

se = strel('disk',radius,decomposition);

BW = imerode(BW, se);

maskedImageXY = I;

maskedImageXY(~BW) = 0;

% figure

% imshow(maskedImageXY)

output_folder='D:\payanname\New folder';

myImage = imresize(maskedImageXY,[500 500]);

outputFileName = fullfile(output_folder,[sprintf('%d.png',ii)]);

imwrite(myImage, outputFileName);

end
