You say you have "successfully attained the edges of each feature seperately". So all you have to do it call hold on and then plot.

hold on
plot(x, y, 'r-', 'LineWidth', 2);

If you don't have the edges in a list of x and y coordinates, then you need to get them, like by calling bwboundaries() on the original binary image.

Thank you sir. This code also help me plot the boundaries with different colour.
