you can use one of the four feature groups without modifying the config file by using separate normalization and then blocking feature groups. This would only use any combination of the implemented four feature types. This is also described in the MRML papers and in the perl script for querying.
Adding other features would indeed be more complicated.

Hi David,

I found in your Perl client, it is able to select a algorithm from a

I also want to make a selection of algorithms like filtering by color
only, by texture only, and by combination of color and texture. Can
you tell me how I can achieve this?
Should this be done by using, or by running
gift server, or make any configuration changes?

You need to edit $GIFT_HOME/gift-config.mrml

This is beyond basic use though.

By the way, by using GIFT, can we match images by color, pattern, and
shape separately? or a combination of two or three of these three

GIFT has no shape features. You need to read the original Viper papers
to understand the colour and texture features that GIFT uses. See the
1999-2000 papers at,
for example.
