image recognition

[Anoopnegi]

if i have to make a c program for image recognition which algorithm i must follow n how can i implements that technique in c programming.
either to use openGl libraries.

What do you mean "image recognition". Please provide more detailed information about your question.

Also in proper English please :P

image recoznition mean reccoz some one by its image. to make machine smart enough.

So you want to have a picture of someone's face and the program is supposed to tell you who it is?

P.S. I always thought image recognition meant getting text (strings) out of an image

Recognize? Is that what it is?

Hi Anoopnegi!

I did some kind of character recognition stuff (long back ...its and old topic now), also face recognition, head nod and head shake recognition, eye....gaze.........................., and also my collegue is doing research on traffic light and zebra crossing recognition for blind people :)

So, if you only say image recognition, its not that much informative :) Can you clarify what you really want do?

This field is more related to image processing and machine learning and both of them are huge areas:)

And if you want to do something on this track quickly, then chossing openCV (http://sourceforge.net/projects/opencvlibrary/) is a good choice. Just have a google search using opencv, u will find lots of thing related to object recognition from image :)

Hope it helps..

Hey, I've seen worse from some of the Mods here. At least is isn't some really bad l337 crap. Though I don't approve of using single letters in place of words.

Image recognition means recognising an image, be it text or a face or something else. It is pretty cool stuff. Some of the techniques can be applied to image compression.

hi..
i am working on a project where I am supposed to write a C code for reconising a person, using a webcam..the individual would be facing the cam and I have to verify if the face of the person matches with my database of images...

I was reading about use of eigen faces in doing so..but i am having a lot of trouble..any help??

What kind of trouble?

I don't have any experence, but I am fairly good at algorithms and design of such. Here is a link that I found when I googled 'eigen faces'. If I were to help you, this is how I would find such info.

thanks a lot dude..
was of great help...
one more thing...
can u tell me an exact procedure for doing camera callibration using OPENCV library..I read the tutorials but of no avail..
any help would be highly helpful

Sorry, I would just point you at documentation. I have no experience with it.

Good luck

Hi leoheel!

What do you really mean by camera calibration?

this [url=http://opencvlibrary.sourceforge.net/FaceDetection] might be useful.

It gets input from the camera or webcam (or avi file) and detects face on live video input (or avi movie) using Haar classifier.
