Igray = rgb2gray(I);
BW = im2bw(Igray,graythresh(Igray));
imshow(BW)

Tinker with this threshold value:
threshold = 250;
A = imread('export_fig_out.png');
A(A>=threshold)=255;
A(A<threshold)=0;
imshow(A)

Before adjusting the image, (if you have the image processing toolbox) try imhist(A) to see where values in A lie relative to the gray scale.
