figure;imshow(Ims);
hold on
for k = 1:length(B)
boundary = B{k};
plot(boundary(:,2), boundary(:,1), 'k', 'LineWidth', 2)
end
I want the image in the figure to be save as png file via code,not by using save as option from figure
have used saveas but it print entire figur in png format,iwant the image of original sized to be saved

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.
