how to add or embed numbers (e.g 1 2 3 ...) into a binary image?

I have a binary image of a blood cell, I want to insert numbering into that binary image. For color or gray image we can use inserttext command, but its not working on binary image. Please help

what exactly is your goal? do you want to insert binary numbers into the binary image or are you ok with a binary image as base and insertion of a truecolor numbering like

im=zeros(100,100);
im(:,35)=1; im(:, 46)=1; im(46,:)=1;
im=im==1;
imshow(insertText(double(im),[50 50],'hello'));

if you really need a binary image you can insert a white (or black) text without a colored box and do some conversion

im=rgb2gray(insertText(double(im),[50 50],'hello','BoxOpacity',0,'TextColor','white'));

im=im>0.6 % to sharpen the the blury inserted text
imshow(im);
