I = imread('img.bmp'); I_bin = im2bw(I);
% find the '0's in the image:
a = find(I_bin==0);
% find the '1's in the image:
b = find(I_bin==1);

I'm not sure what you're going to do, just having linear indices of where it is 1 and where it is 0 is virtually never required. You're probably heading down an inefficient path but since you didn't give the complete context, I don't know how to tell you the best way to proceed. Explain more about your application, and I'll tell you the right way to do it.
