% Start by padding the image with 0s on the left, top, and right.
bw2 = padarray(bw,[1 0],0,'pre');
bw3 = padarray(bw2,[0 1],0,'both');
% Remove objects touching the border of the padded image.
bw4 = imclearborder(bw3);
% Remove the padded columns and padded row.
bw5 = bw4(2:end,2:end-1);

Yes, it will remove only the objects connected to the lower border. That's the reason for the first two lines (padding the image) and the last line (removing the padded columns and row). Follow the link to my blog post for more explanation about this technique.
