Yup. Thanks for that.

I suspect that what I'm doing above isn't quite the same as disabling the
other features in a GUI interface though.
Here's my xml query using only colour blocks:
<algorithm
algorithm-id="a-cidf"
algorithm-type="adefault"
collection-id="c-37-46-17-21-6-105-4-201-0"
cui-block-color-histogram="true"
cui-block-color-blocks="false"
cui-block-texture-histogram="true"
cui-block-texture-blocks="true"
cui-pr-percentage-of-features="70" >
</algorithm>
Here's the xml query that's generated by GIFT's GUI interface. I disabled
all the features except for colour blocks:
<algorithm
algorithm-id="a-cidf"
algorithm-type="a-cidf"
collection-id="c-37-46-17-21-6-105-4-201-0"
cui-pr-percentage-of-features="70"
cui-block-color-blocks="false"
cui-block-texture-blocks="true"
cui-block-texture-histogram="true"
cui-block-color-histogram="true" >
</algorithm>
With the latter query, the similarity scores exceed 0.25, which tells me that
it's using more than just one out of four features. However, if I changed the
"algorithm-type" to "a-cidf" for the former query, I would then get the the
same similarity scores. Can you please shed some light?
Thanks,
Jun Jie
