 a=imread('cameraman.tif');
 [c,h]=contour(a,4);

now what c represents can I used for plotting contours without using contor function in matlab? Or In other word How can I store the contour boundary or locations , so I can used those data afterwards???????????????????/

The C2xyz function does this simply.

Yes, if you read through http://www.mathworks.com/help/matlab/creating_plots/contour-plots.html#f10-2614 you will find a description of the structure of a contour matrix.
