Hi Surendra,
Have you looked into the "imcontour" function?
imcontour(I) draws a contour plot of the grayscale image I, choosing the number of levels and the values of levels automatically.
Attaching an example and documentation for your perusal.

Other functions/workflows that you might find useful depending on your case:
