IMCONTOUR Create contour plot of image data.
    IMCONTOUR(I) draws a contour plot of the intensity image I,
    automatically setting up the axes so their orientation and aspect
    ratio match the image.

    IMCONTOUR(I,N) draws a contour plot of the intensity image I,
    automatically setting up the axes so their orientation and
    aspect ratio match the image. N is the number of equally
    spaced contour levels in the plot; if you omit the argument,
    the number of levels and the values of the levels are chosen
    automatically.

    IMCONTOUR(I,V) draws a contour plot of I with contour lines
    at the data values specified in vector V. The number of
    contour levels is equal to length(V).

    IMCONTOUR(X,Y,...) uses the vectors X and Y to specify the x-
    and y-axis limits.

    IMCONTOUR(...,LINESPEC) draws the contours using the line
    type and color specified by LINESPEC. Marker symbols are
    ignored.

    [C,H] = IMCONTOUR(...) returns the contour matrix C and a vector of
    handles to the objects in the plot. (The objects are actually patches, and
    the lines are the edges of the patches.) You can use the CLABEL function
    with the contour matrix C to add contour labels to the plot.

    Class Support
    -------------
    The input image can be uint8, uint16, int16, double, single, or logical.

    Example
    -------
        I = imread('circuit.tif');
        imcontour(I,3)

    See also clabel, contour.
