please explain the this piece of code
label=bwlabel(sout);
stats=regionprops(logical(sout),'Solidity','Area','BoundingBox');
density=[stats.Solidity];
area=[stats.Area];
high_dense_area=density>0.6;
max_area=max(area(high_dense_area));
tumor_label=find(area==max_area);
tumor=ismember(label,tumor_label);
if max_area>100
figure;
imshow(tumor)
title('tumor alone','FontSize',20);
else
h = msgbox('No Tumor!!','status');
%disp('no tumor');
return;
end

Hi,
In the code mentioned above, we use bwlabel to find connected components within the image and attach labels to the connected components.We calculate the density and area of individual connected regions. Then we find the region with the maximum area and in that particular region, we filter out pixels with density grater than 0.6.
These pixels are identified as the tumor pixels if the maximum area is 100, else we conclude that there is no tumor region in the image.
Hope this helps!
