hi,
i have built a PHP interface for gift that correctly parses all the mrml
interactions (not like the interface on the viper pages that incorrectly
analyses the sub algorithms).
it seems that the 'cui-block-color-blocks' attribute can lead to an empty
result if it is set to 'true' on the server available at viper.unige.ch.
here is the request i run:
<?xml version="1.0" standalone="no"?><!DOCTYPE mrml SYSTEM
"http://isrpc85.epfl.ch/Charmer/code/mrml.dtd"> <mrml
session-id="b32158d8-a626-4802-868c-6f55e41d1cb9"> <configure-session
session-id="b32158d8-a626-4802-868c-6f55e41d1cb9"> <algorithm
algorithm-id="a-cidf" algorithm-type="a-cidf"
collection-id="c-4-42-22-20-4-103-2-139-0" cui-pr-percentage-of-features="70"
cui-block-color-blocks="true" cui-block-texture-blocks="false"
cui-block-texture-histogram="false" cui-block-color-histogram="false" >
</algorithm> </configure-session> <query-step
session-id="b32158d8-a626-4802-868c-6f55e41d1cb9" result-size="10"
result-cutoff="0.0" collection="c-4-42-22-20-4-103-2-139-0"
algorithm-id="a-cidf"> <mpeg-7-qbe></mpeg-7-qbe>
<user-relevance-element-list> <user-relevance-element
image-location="http://viper.unige.ch/images/corel/photographs_thumbnails/various_textures/593098_thumbnail_jpg.jpg"
thumbnail-location=""
user-relevance="1"/></user-relevance-element-list></query-step></mrml>
and the result i get:
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <mrml
just-for-test="and-of-course-for-fun"
session-id="b32158d8-a626-4802-868c-6f55e41d1cb9" > <cui-time-stamp
calendar-time="Fri Jul 9 11:28:45 2004 " /> <acknowledge-session-op
session-id="b32158d8-a626-4802-868c-6f55e41d1cb9" /> <query-result >
<query-result-element-list /> </query-result> <cui-time-stamp
calendar-time="Fri Jul 9 11:28:45 2004 " /> </mrml>
i receive the same error for the other images i tried.
when blocking another feature group or even all three others the system
delivers correct results.
i have a local version of gift-0.1.11 installed and here it seems to work
properly.
any ideas on what the problem might be?
regards,
joris
