Take photographs of your hands - for the sake of programming!

I'm messing around with OpenCV and Haar Cascade functions. Being able to detect faces and bodies on camera is neat, I've had some fun making my laptop lock & unlock when people are nearby, stuff like that.
Another thing I've been doing is dicking around with multitouch ideas - then I had the idea to combine the two things. I got fed up of tracking markers and stuff. I'd rather be able to do shit with hand gestures.
So, I'm using Haar Cascade Classifiers to do this.
I need a fuckton of clean images of hands, from a bunch of angles (mostly frontal).
Anyone want to help me with this?
[b]I need clear, reasonable-sized (640x480), grayscale, JPEGS of hands, lit well from in front (by a computer screen is fine), preferably on a [b]black[/b] background, like this:[/b] (thanks ASH D)

Except it'd be better if they were rotated 90 degrees clockwise from that (just hands straight out, like you're signing 'STOP!'). This is because the classifier needs to be able to detect hands in their most likely-to-appear gestures.
It would also be useful to get photographs of your hand [b]in a fist[/b], as well.
I'm posting a thread about it because there's no way I'm gonna get thousands of images of hands just by myself... I can get about 400 images if I got everyone in my college to photograph their hands, haha.
DO IT FOR SCIENCE!
UPDATE: So far I have 47 images of me and my two friends' hands. It's a start ;p
I'm happy to do this if I can get my webcam working, I'll try and get it just now.

I have pretty big bassist hands by the way.

Heh that's fine. I need a variety of different hand shapes, sizes etc. so it detects anyone's, not just mine. If you could get a few shots of your hands on a blank background, from a couple angles (front, back, etc.) that'd be good.
Is this some crazy scheme to fulfill your hand fetish?

I'll take a few, not sure where to find a blank background
You could use a blank bit of paper surely.

will this do?
I can't get my webcam to work :argh:. I'll try my laptop later tonight, unless you are in a hurry. Sorry.
i would but my webcams quality is ass

More like you have lady hands
It has been known that efeX has small girlish hands
I'd suggest using black cloth or construction paper. White might not be enough contrast.

1 Photograph of my hand as requested.

Please be joking ...
Thanks to Grimezy and qurl for posting photos, those are -exactly- what I mean.
I may start a site to collect these images and then post about it on Digg/reddit/etc.... I need a lot of hands ;P
Keep posting, people!

It rotated for some reason.
It'll look better when you re-size it.
Better

Flash works best

Sounds like a really cool idea.
Do you need both left and right hands?
I'll take some in a bit for you.

We can see your sweaty palms on the last one.
Brb shaving palms :smug:
Ugh, need to wait till tomorrow so I can buy batteries :\.

It's hot in the basement :c
[QUOTE=efeX;17870030]lol ur thumb is weird[/QUOTE]
It's called having no tan to cover.
I don't think you should be bending your thumbs back in the pictures.
[QUOTE=nos217;17874606]I don't think you should be bending your thumbs back in the pictures.[/QUOTE]
It's alright, having a few weird-shaped hand gestures in the collection of photos will help the haar cascade classifier; it'll be able to detect hands when you've dislocated your thumb ;P
I've found a classifier for hands, which I didn't make, but it's absolutely shit... it only detects the palms of your hands, and only when the webcam's facing a blank wall. So I still am gonna need to train my own classifier.
I'll collect the hand images I've got from this thread. Keep 'em coming!
Haar Cascade functions? I hope you're prepared for unexpected consequences...
Here's an idea. Take a picture of your hand...outside!

We don't go outside :ohdear:
