Hi all
i just try adaptive method for segmentation.
but i want to know what does mean by this coding
I = imread('rice.png');
BW = imbinarize(I,T);
T = adaptthresh(I, 0.4);
figure
imshowpair(I, BW, 'montage')
what is 0.4 mean?
is it percentage? 40%?

They call that the sensitivity. Not really sure what it means without digging into the algorithm, but basically try different values until it works like you want. Some values may do a better job at segmentation than others.
