Hello out there,
I'm trying to figure out how I can find the ten best matching images
to a given image. The documentation of Oracle Multimedia (for
11.2.0.2) gives nearly no examples for this.
I think I have to use SI_Stillimage and SI_Featurelist to satisfy my
needs, but my approach so far is not very performant.
I use SI_FeatureList.SI_Score to compute the matching score and I have
to do that for every image in the database.
Is there a better (i.e. faster) solution for that? I would like to
index the featurelist to speedup similarity searches but since my
approach uses the SI_Score function, any index on the featurelist does
not help.
Has anyone experience with content based image retrieval using
SI_Stillimage and its companions and can give me a few hints?

Many thanks in advance,
Lothar
