for k = 1:length(B)
boundary = B{k};
plot(boundary(:,2), boundary(:,1), 'k', 'LineWidth', 2)

Write to the image instead of plotting over it in the overlay :
imshow(Ims);
hold on
for k = 1:length(B)
thisBoundary = B{k};
rows = thisBoundary(:, 1);
columns = thisBoundary(:, 2);
for p = 1 : length(rows)
thisRow = rows(p);
thisColumn = columns(p);
Ims(thisRow, thisColumn, :) = uint8([0, 0, 0]);
end
end
imshow(Ims);
drawnow;
imwrite(Ims, filename);
If you want thicker lines, you'll have to write in a region around thisRow, thisColumn instead of just doing the single pixel.

That's what it does. imwrite() does not add any extra stuff around it like hgsave(), export_fig(), saveas(), etc.
