Can anyone please help me?

The program I'm working on is for Facial Recognition using Neural Networks. The thing I'm having problems with though is processing the image of a face in order to be able to read it into the Network.
I have a greyscale bitmap image of a person's head, with background (it's basically a B&W portrait photo like for a Passport), and I want to process it to just get a pure white image with the edges/feature-outlines of the original image in pure black.

I'm pretty new to programming, so any pseudocode/tips/ideas would be greatly appreciated.

Thanks

hi,

I'm not sure if I perfectly understood your question but, I think you're gonna have to user a filter on your image. I had to do a similar task in order to eliminate many levels of gray on an image.

It can be a bit confusing though, but I once found a perfect program to test filters and I found it very useful. It was also open source and made in delphi.

Unfortunately, I don't have the url with me right now, but I'd be glad to look it up for you if you are interested.

I could also give you a more complete explanation of how to pass a filter into an image with delphi and maybe show you my code.
Best way to reach me is at Geenie@videotron.ca as I receive so much junk in hotmail right now that I can't even tell wich mails aren't.
