Ask the hive mind - A program to match pictures

In an attempt to put some order in some of my harddrives, I figure I need to strip some of the various duplicates that I have. For music I've used media monkey in the past, which was ok. I've also used Fslint for just a generic "do these files match" approach. I know there are now programs which supposedly match pictures based on face recognition or other such criteria, which could be very useful when I have multiple copies of something similar at different resolutions. Does anyone have any experience with any of these? Any recommendations for a balance between usefulness and cost for those of us who are desperately poor?

I could make the "welcome back from surgery" meal for only one of those who went in today, so it is tweaked for my father's preferences.

Primo - Avocado and Pepper salad with a mustard vinagrette

- One avocado, in manageable slices
- One orange bell pepper
- One yellow bell pepper
- Greens
- Tiny heirloom tomatoes.
- The bits of mustard that cling to the jar after you've used it normally.
- Honey wine vinegar
- Olive oil

Cut up the vegetables, make sure to rub some citrus on the avocado to keep it from going brown. Mix with the greens. Pour some olive oil into the mustard jar, shake to mix. Pour on salad. Pour some vinegar into jar to gather last parts of the mustard, shake to mix. Pour on salad.

Serve.

Secondo - Bavette of Bison with mushroom accompanied by Oven-roasted winter vegetables.

Marinate bison overnight. Brown both sides of bison at medium-high heat. (A few minutes each side.) Add some stock made from game along with the marinade. Cook in low heat for an hour and a half. About 20-25 minutes before the end, add in a handful of chopped shitake and pleurot mushrooms.

Cut up carrots, turnips, potatoes, and onions into smallish pieces. Toss with olive oil, salt, pepper, marjoram. Add cloves of garlic, unpeeled, and ginger cut into small matchsticks. Cook at 375 for an hour or so.

Dessert
Raspberries in a chocolate heart with 16-year Glenlivet Nadurra scotch.
