Software for determining image similarity?

This is a lazyweb request – I’m looking for something but I don’t even know if it exists. I have about 200 photos (headshots) and I’d like to make an animation that runs through them in order of, for lack of a better term, visual similarity. I’m not talking about morphing or just fading between the images in arbitrary order. Is there software out there that, given a reference image and a set of images to select from, can choose the most similar image?

Aperture

Today Apple announced their new imaging application, Aperture. This is clearly intended to be a high-end app, and Apple wants to make sure you get that. “Aperture: Designed for Professional Photographers.” A retail price of $499 ($249 educational). A website that reads: “Whether you’re a fashion, wedding, sports, portrait, fine art, commercial, or editorial photographer…” And the recommended minimum hardware: dual 2GHz G5 PowerMac with 2GB of RAM. It’s more of an image processing application than an image editing application – pixel-level editing tools are scarce in Aperture.
