Re: [help-GIFT] Using GIFT for symbol recognition

[Wolfgang Müller]

Hi,

In addition to what David and Henning said, I think it pretty much depends 
what you want to pick out.

David and Henning mainly spoke about symbols that make up the whole image 
(unless I grossly misunderstood you, folks), like:

 ----
|888 |
 ----

GIFT would probably be able to pick out that the image consists mainly of 
these 3 "8" symbols. Other images which mainly consist of 3 "8" symbols will 
be regarded similar by the GIFT.

However, it would *not* be able to pick out every "8" in an image regardless 
of number, location and orientation of "8"s. This would need considerable 
changes in the feature extraction algorithms.

Cheers,
Wolfgang
