They're not the same shape so there will be some pixels that will be misaligned. Do you want to align only the bottoms, and not overall?

Yes, I know they have different shape, but I want to all of them have the same bottom. Align only the bottoms. Is there any way??

I don't knwo what align means to you but how about you pick one column and find where the last row is

lastRow = find(binaryImage(column, :), 1, 'last');

Then do that for all other images and use circshift to vertically shift them so that they all have their last row at the same row. Something like (untested)

deltaY = lastRow2 - lastRow;
binaryImage2 = circshift(binaryImage2, [1, deltaY]);
