imcontour() - Image Processing

imcontour(I) draws a contour plot of the
grayscale 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 grayscale 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,handle] = imcontour(...) returns the
contour matrix C and a handle to an hggroup object.

Syntax

imcontour(I)imcontour(I,n)imcontour(I,v)imcontour(x,y,...)imcontour(...,LineSpec)[C,handle] = imcontour(...)

Example

I = imread('circuit.tif');
