If your image is an indexed or grayscale image, it is just a matter of comparing the image to a pre-defined threshold. You will need to adjust this threshold based on which features of the image you want to be a 1.

threshold = 0.5;  %or some other threshold
BW = (myImage >= threshold);   %this will be a matrix of ones and zeros.
