visual search in image database

Post by Bernard Zwischenbrugge » Tue, 11 Jul 1995 04:00:00


i have a database with more than 1000 images (photos of persons).
some of this photos are equivalent and if i add new photos to the
database, i have to search if the image already is in the database because i
want it only one time.
how can i do that?

Pixel by Pixel ? (to slow)
compare only the histogramms.

has anybody worked (or is working) on a similar project.

i already implemented the normalization of the pictures:
  rotation (if the borders of the image are not parallel to the border of
            picture in the image),
  border cut (we scan all the pictures with a white border),
  histogramm equalization,
  and some compare methodes,

Im looking for complete C-code, statistics ....
all that helps me doing my project.
