SUMMARY Currently, stats show only the number of pictures for each filetype. This could be enhanced so that the following statics about face tags/people are shown: total number of people total number of face tags average number of face tags per picture number facetags of person with highest number of facetags average number of facetags per person number of facetags of person with lowest number of facetags
As far as I know, this would take a while for the calculation of this numbers. I don't understand the value of same of this stat information as face taging still deals with a lot of undetected faces. But I agree, it would be nice to have some stat data of people. The program Picasa did it very well in my opinion. They showed after each name tag the number of assigned tags and they sorted the tags by default according to the amount of tags. This would already provide you a lot of information.
Marcel, The total statistics about number of face tags can be certainly processed internally with SQL through the database. A database must be fast for this kind of request. For other, i agree this can be more CPU idle... This need to be tested of course... Note : we have already this kind of stats for each face tags when option to count of items in tree-view is enabled from Setup dialog. Gilles
