VLFeat

VLFeat on Octave.

"David, I heard you wrote some VLFeat stuff for Octave. Any news?"

Yes. I've done some patching to make it work with Octave 3.3+. Note that 
the Octave/mex interface is NOT ABI compatible with Matlab/mex! So you 
can't use Matlab's mex compiler to make binaries for Octave. You'll have 
to use mkoctfile --mex.

Note that there are some fixes AFTER Octave 3.2 to the Octave/mex 
interface. Search for my name in the Octave hg repository.

I'm attaching all commits I've written for VLFeat. Some of them are 
crucial, some of them are stupid and can safely be ignored. There are 
some multi-threading thrown in too. The focus has been on vl_sift and 
vl_ubcmatch.

I'm licensing these patches under GPLv2+. They may only be used under 
the terms of GPLv2 or, at your choice, any later version. (I believe 
this is the license for VLFeat too, at least I asked the authors to add 
the "and later" clause, and I think I was successful)

Here's the pathetic excuse for building system I used:

set -eu
cd toolbox/sift
for FILE in vl*.c ;
do
    mkoctfile "$FILE" -I../  -I../misc -I../../ ../../vl/*.c --mex \
        -D__LITTLE_ENDIAN__
#-DHAVE_PTHREAD -pthread
#a,p,c
# -DVL_SUPPORT_SSE2
done

That's most of it.

David
