Here is an example to obtain low intensities. It is often handy to keep the original format and set the elements you are not interested in to NaN or some other arbitrary value.
AllImage = rand(6,5) % smaller example
tf = AllImage < 0.4
lowImage = nan(size(AllImage))
lowImage(tf) = AllImage(tf)
ValuesOnly = AllImage(tf)

if (x<0.4)
...do anything
elseif (x>=0.4 | x<=0.7)
...do another thing
else % this is for x>0.7
...whatever
end
