doubt 1:
in this algorithm,
Lowe shows 3 intervals on each
pyramid level is the best, but 2 is also reliably good. .. so actually what does the term "interval" refers too ?
doubt 2:
for example:
 we have 4 scales per octave , then we would blur the image and proceed it for DOG(we would get 3 scales per octave). we ill obtain the keypoints.
my doubt is whether process would be stopped here or again that 3 scales per octave would be reduced to 2 per octave ? process goes on ?...
my mail id is mydreamprojects@yahoo.com...............
pls kindly any one post some reply for it. pls pls

I don't see anything MATLAB-related here.
Perhaps you meant to post in sci.image.processing?
