**Displaying a Contour Plot of Image Data**

You can use the toolbox function `imcontour`

to display a contour plot of the data in a grayscale image. A contour is a path in an image along which the image intensity values are equal to a constant. This function is similar to the `contour`

function in MATLAB, but it automatically sets up the axes so their orientation and aspect ratio match the image.

This example displays a grayscale image of grains of rice and a contour plot of the image data:

You can use the `clabel`

function to label the levels of the contours. See the description of `clabel`

in the MATLAB Function Reference for details.
