How are you saving it. You're probably using save() or saveas() instead of imwrite(). Don't save the figure, which will have a border. Just save the image array only .

fh = figure('Menu','none','ToolBar','none'); 
ah = axes('Units','Normalize','Position',[0 0 1 1])

ADDENDUM

If you're using axis square you'll need to make sure the figure position is also square. Here's a demo following the block above:

plot(rand(1000,1),rand(1000,1),'ko')
axis(ah, 'square')
fh.Position(3) = fh.Position(4);  %set width equal to height

The saved image must be rectangular, no matter what your freehand ROI looks like, but the outer layer of pixels shouldn't be white unless you're cropping the image and then setting them white. You are using imwrite() to save the cropped portion aren't you?
