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

[Philip Farrugia]

Hi,

Thank you for your post. As you indicated my interest is about symbols making up the whole image. Basically, what I want from GIFT is that it returns a label for an input image of *one* symbol. Obviously,  I'd need to create my own set of images in the database.

Please do bear with me.. I'm new to GIFT...kindly can you indicate any user's manual to get familiar in using the code of this software? For instance, how to index a directory structure containing my set of images?

Thanks in advance for your help.

Best Regards,

Philip

Can you please tell me whether it is possible to recognise hand-drawn
symbols using GIFT? If yes, how to create my own database of symbols in
GIFT?
    

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
