BTW, I do think that not rescaling will cause serious problems, since
the feature extraction code is premised on 16x16 blocks at the lowest
level, and using images of different sizes will result in the same block
feature ID being used to refer to different image locations for
different images. IDs are assigned simply by counting.
Yes, this is clear. To translate: all images of one collection are to be
resized to the same size. However, changing this size is not a problem
(within limits). Right?
Yes, with rewritten feature extraction code, this should be fine. The
current code in GIFT has '256' hard-coded into it though.
The best solution would probably be to rewrite the code so that it used
a fixed depth quadtree, but tolerated non-square blocks. This would also
have the advantage the texture distortions through the rescaling of
non-square images would be avoided.
