Hello, I have an image from type double and i want to convert it to binary format with my threshold. Then I try this code:
for i=1:426
for j=1:640
if IM(i,j)>100
bw(i,j)=250
elseif IM(i,j)<100
bw(i,j) =1
end
end
end
it doesn't work.
another way: bw= IM > 100; also doesn't work/ can u help me? thnx
P.S. I can't use this ways only then i work in type - double
