<p>These instructions explain how to use VLFeat from the command line |
|
|
(shell).</p> |
|
|
|
|
|
<p><a href="%pathto:download;">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>The command line tools are located |
|
|
in <code>VLFEATROOT/bin/ARCH</code>. Here <code>ARCH</code> denotes |
|
|
the subdirectory relative to your architecture (e.g. <code>mac</code> |
|
|
for Mac OS X PPC, <code>maci</code> for Mac OS X |
|
|
Intel, <code>glx</code> for Linux, and so on). For instance, to run |
|
|
the SIFT feature extraction code type</p> |

<p>All commands have a corresponding man page found |
|
|
in <code>VLFEATROOT/src</code>. For UNIX based systems, the man pages |
|
|
can be viewed with the <code>man</code> utility. For instance |
|
|
</p> |
|
|
|
|
|
<pre> |
|
|
> man VLFEATROOT/src/sift.1 |
|
|
</pre> |
|
|
|
|
|
|
|
|
<p>It might be convenient to add VLFeat to the system search paths. In |
|
|
Linux and Mac OS X this involves modifying the <code>PATH</code> |
|
|
and <code>MANPATH</code> environment variables. The exact details may |
|
|
vary, but it should be enough to add the following to your |
|
|
<code>~/.bash_profile</code>:</p> |
|
|
|
|
|
<pre> |
|
|
export PATH=VLFEATROOT/bin/ARCH:$PATH |
|
|
export MANPATH=VLFEATROOT/src:$MANPATH |
|
|
</pre> |
|
|
|
|
|
<p>Alternatively, you can copy the executables and man pages to |
|
|
appropriate system-wide directories.</p> |
