Why you cannot use imfill?

The holes aren't really holes but are actually bays at the top and bottom of the image. What you'll have to do to fill those is to draw a line at the top and bottom of the image and call imfill, then erase the lines afterwards.

binaryImage(1,:) = true;
binaryImage(end,:) = true;
binaryImage = imfill(binaryImage, 'holes');
binaryImage(1,:) = false;
binaryImage(end,:) = false;
