Re: Implementing SIFT algorithm

[pavan padmashali]

I'm a beginner, so I just tried implementing David Lowe's SIFT line by line. In that, so as to understand the working rather than blankly try to understand the theory. Then ,i encountered parse errors which indicated syntax error showing various areas I had the location of a siftWin32.exe file. I have stopped here. Should I go a round about trying to implement SIFT any other way?

What do you mean? Do you want to run David Lowe's code in Octave or do
you want to implement SIFT from scratch? From what I recall, David
Lowe's code is just a simple wrapper around a binary program so that
should easily run in Octave. If you want to re-implement SIFT in Octave,
I recommend against it: the algorithm is ridiculously hard to implement
if you want it to behave like David Lowe's implementation (you need to
get a bunch of tweaks just right or nothing works).
