Re: [help-GIFT] How to make a algorithm selection

[zhigao pu]

Hi Henning and David,

       Can you please provide me some examples or files showing how to do this algorithm configuration.

       I will read the paper later. What I want to do is to provide algorithms of color only, texture only, or color combined with texture.  Is this possible?    

       What do you mean by "Adding other features" and why it is difficult?

       My understanding is that the configuration of algorithms selection will not affect the gift-add-collection operation, and I do not need to do the indexing again, right?

       Thanks

Zhigao
