/** \page ExampleList Examples
Demonstration programs for VIGRA's usage.
Click on the hyperlinks to view the commented source code for the demos.
Most examples can be applied to both gray-scale and RGB images.
See <a href="Installation.html">Installation</a> for instructions on how these
programs can be compiled. For convenience, the directory contains the test images
<a href="lenna_gray.gif">lenna_gray.gif</a> and
<a href="lenna_color.gif">lenna_color.gif</a>.
<ul>
<li> Convert an image file into another file type:
<a href="convert_8cxx-example.html">convert.cxx</a> <br>

<a href="smooth_8cxx-example.html">smooth.cxx</a> <br>
Usage: <TT>example_smooth infile outfile</TT>
<li> Find the gray value profile along the image diagonal
by means of a \ref vigra::LineIterator :
<a href="profile_8cxx-example.html">profile.cxx</a> <br>
Usage: <TT>example_profile infile</TT>, generates <TT>profile.gif</TT>
<li> Create series of slices through different color spaces.:
<a href="palette_8cxx-example.html">palette.cxx</a> <br>
Usage: <TT>example_palette lab</TT>, generates <TT>lab_*.gif</TT> (44 images)
<li> Reduce image size by mean of a Gaussian pyramid:
<a href="pyramid_8cxx-example.html">pyramid.cxx</a> <br>
Usage: <TT>example_pyramid infile outfile</TT>
<li> Find edges by means of a
\ref differenceOfExponentialEdgeImage():
<a href="edge_8cxx-example.html">edge.cxx</a> <br>
Usage: <TT>example_edge infile outfile</TT>
<li> Segment image by means of the watershed algorithm, using
\ref seededRegionGrowing():
<a href="watershed_8cxx-example.html">watershed.cxx</a> <br>
Usage: <TT>example_watershed infile outfile</TT>
<li> Generate a Voronoi diagram, using \ref distanceTransform() and
\ref seededRegionGrowing():

Usage: <TT>example_voronoi</TT>, generates: <TT>distances.gif</TT> (Euclidean distance transform) and <TT>voronoi.gif</TT>
(Voronoi diagram)
<li> Measure boundary and corner strengths with the
\ref boundaryTensor():
<a href="example_boundarytensor_8cxx-example.html">boundarytensor.cxx</a> <br>
Usage: <TT>boundarytensor infile</TT>, creates <tt>boundarystrength.tif</tt> and <tt>cornerstrength.tif</tt>
<li> Total Variation (TV) Regularization
<a href="total_variation_8cxx-example.html">total_variation.cxx</a> <br>
Usage: <TT>example_total_variation parameterfile</TT>
