These instructions explain how to setup VLFeat in MATLAB using the binary distribution (it is also possible to compile the library and toolbox from source).
One-time setup
Download and unpack the latest
VLFeat binary distribution in a directory of your choice
(e.g. ~/src/vlfeat). Let VLFEATROOT denote
this directory. VLFeat must be added to MATLAB search path by running
the vl_setup command found in
the VLFEATROOT/toolbox directory. From MATLAB prompt
enter
>> run('VLFEATROOT/toolbox/vl_setup')
VLFeat 0.9.8 ready.
To check that VLFeat is sucessfully installed, try to run
the vl_version command:
>> vl_version verbose
VLFeat version 0.9.8
Static config: X64, little_endian, GNU C 40201 LP64, POSIX_threads, SSE2
4 CPU(s): GenuineIntel MMX SSE SSE2 SSE3 SSE41 SSE42
SIMD enabled: yes
Permanent setup
To permanently add VLFeat to your MATLAB environment, add this line
to your
startup.m
file:
run('VLFEATROOT/toolbox/vl_setup')
When you restart MATLAB, you should see the VLFeat greeting message.
Getting started
All commands embed interface documentation that can be viewed with
the
builtin help
command (e.g. help vl_sift).
VLFeat bundles a large number of demos. To use them, add the demo
path with vl_setup demo. For example, a sift demo
vl_demo_sift_basic can be run using the following:
>> vl_setup demo
>> vl_demo_sift_basic
To see a list of demos TAB-complete vl_demo at MATLAB
prompt, after running vl_setup demo.
