Reset iPhoto ’09 face recognition database

Edit: Solution in the comments.

I’ve been playing around with the iPhoto ’09 face detection and face recognition stuff today. Having tried a lot of stuff to get the best results, I now want to “reset” the face recognition database or whatever so that I can start from scratch and teach it properly. Does anyone have any idea how to do this apart from emptying my library and re-importing everything again? There must be a way, right?

    Quit, remove the files “faces_blob.db” and “faces.db” from the iPhoto library, and restart. Should do the trick.

    That did indeed do the trick. Thanks!

    Indeed, thank you Mange!

    Should be noted that you need to right-click on the iPhoto Library and select “Show Package Contents” in order to view/remove these .db files.

    Ok. What about deleting just a few faces? Is there a possibility? Any suggestion? Thanks

    I doubt it, Sandro. You would have to edit the faces database for that. It’s probably doable, but it would involve a lot of trickery.

    Just a correction, the files seem to be face_blob.db and faces.db. Thanks for the tip however, it was very helpful.

    Thanks for the tip. Any optimization of iPhoto is good. It’s sooo slow.

    You can indeed delete faces individually, I think Command+Delete does the trick, don’t really know if it deletes databases or just stops the face from showing up…

    you can delete single faces by dragging them to the trash in iphoto. and where might these face files be found so as to delete them?
