This wiki site is setup for organizing the sharing of elements between TRECVid participants.
It is started primarily for the 2012 semantic indexing task but it might be extended for other issues and/or other tasks.
We propose to reuse and extend the organization that has been developed over four years within the members of the IRIM project of the French ISIS national Research Group (see the IRIM paper at TRECVid 2011 and 2012). It is based on a limited number of simple data formats and on a (quite) simple directory organization. It also comes with a few scripts and procedures as well as with some sections for reporting intermediate results.
A general rule about the sharing of elements is that:
exactly as this was the case in the previous years for other shared elements like shot segmentation, ASR transcripts or collaborative annotation. Groups sharing elements get “rewarded” via citations when their elements are used. Reward can also be given for instance by sharing back classification scores obtained from descriptors shared by other groups.
Shared elements can be for instance: shot or key frame descriptors, classification results, fusion results.
