Hi...

I like to compare two images such that one should be taken continuously and another should be already stored in memory.

And how to store images...

can you provide more info, what excatly are you comparing in the image. There can be many ways. One of them is to subtract the image. You can also convert your images into array , do the subtraction on those both array and check.

you also might wanna check this : IMAQ compare

The pixels will vary accordingly..Whatever you compare doesnt matter.

Hi...

Thanx for your reply...

But I don't get what you are saying...

I just want to do face recognition by using eigen face vector..

Is it possible to do using labview?

Try this. Why eigen?

Hi...

My idea is to compare two images...

First I have to extract the features such as area of ear,lips,nose and width of forehead and then store in a database..

then I have to capture the image using webcam then extract the features from it and that extracted image data should be

compared with the already stored data in the database...

Is it possible to do??

Do you have the IMAQ library ?

You can do a transposition of the x,y image pixels into a fourier representation.

Subtracting the F-Images you may get the corresponding areas to compare.

But all this is real hard stuff.

Good luck.
