|
<p>These instructions explain how to use VLFeat from |
|
|
MATLAB.</p> |
|
|
|
|
|
<p><a shape="rect" href="download.html">Download</a> and unpack the latest |
|
|
VLFeat binary distribution in a directory of your choice |
|
|
(e.g. <code>~/src/vlfeat</code>). Let <code>VLFEATROOT</code> denote |
|
|
this directory.</p> |
|
|
|
|
|
<p>VLFeat must be added to MATLAB search path by running |
|
|
the <code>vl_setup</code> command found in |
|
|
the <code>VLFEATROOT/toolbox</code> directory. From MATLAB prompt |
|
|
enter</p> |
|
|
|
|
|
<pre xml:space="preserve"> |
|
|
> cd VLFEATROOT |
|
|
> cd toolbox |
|
|
> vl_setup |
|
|
</pre> |
|
|
|
|
|
<p>To avoid name conflicts with other MATLAB commands, all VLFeat |
|
|
commands start with the <code>vl_</code> prefix (for instance the SIFT |
|
|
feature extractor command is called <code>vl_sift</code>). The prefix |
|
|
can be omitted by calling |
|
|
<code>vl_setup('noprefix')</code> instead.</p> |
|
|
|
|
|
<p><code>vl_setup</code> alters the search path for the current MATLAB |
|
|
session only (it does not save the changes). To make the change |
|
|
permanent, add the following fragment to your |
|
|
<a shape="rect" href="http://www.google.com/search?q=site:www.mathworks.com+startup.m&btnI=I"><code>startup.m</code> file</a>:</p> |
|
|
|
|
|
<pre xml:space="preserve"> |
|
|
p=pwd ; |
|
|
cd VLFEATROOT ; |
|
|
cd toolbox ; |
|
|
vl_setup ; |
|
|
cd(p) ; |
|
|
clear p |
|
|
</pre> |
|
|
|
|
|
<p>Alternatively, you can use the |
|
|
<a shape="rect" href="http://www.google.com/search?q=site:www.mathworks.com+savepath&btnI=I"><code>savepath</code> |
|
|
command</a> to save the updated search paths.</p> |
|
|
|
|
|
<p>All commands embed interface documentation that can be viewed with |
|
|
the |
|
|
builtin <a shape="rect" href="http://www.google.com/search?q=site:www.mathworks.com+help&btnI=I"><code>help</code> |
|
|
command</a> (e.g. <code>help vl_sift</code>).</p> |
