Hi,
You can try using BLEAQ2 algorithm, the code for which is available on matlab:

I have a two-level programming model, can you help me with an algorithm code BLEAQ2 in programming the model and finding the final solution?
minF(S1,S2)=1.25*S1^2+4*S2^2
minf(s1,s2)=s1^2+6*s2^2
s.to 2*s1^2+0.6*s2^2 <= 5100000
3*s1^2+4*s2^2 <= 6100000

"The graythresh function uses Otsu's method, which chooses the threshold to minimize the intraclass variance of the black and white pixels."
Otsu, N., "A Threshold Selection Method from Gray-Level Histograms," IEEE Transactions on Systems, Man, and Cybernetics, Vol. 9, No. 1, 1979, pp. 62-66.
