What is Haar Cascade?

[mrzk]

hello everybody
What are Haar Cascades and how am I supposed to use them in Aforge? How can I make one?
Thank you

Hello,

I would start from studying Haar-like features and the rest of Vialo and Jones approach. AForge.NET framework has nothing to do with Haar Cascades for now.

Dear Andrew
I'm trying to detect faces in a picture, that's why I need to use Haar Cascades. as I understand, the only choice for Haar Cascades is OpenCV, but it's hard to understand for me and I think Aforge.net is more user friendly than OpenCV. so I prefer to write my own face detection in Aforge.net. I found some papers about face detection, but there is a statement that I couldn't understand. what's "Cr^2" means? I know what is Cr filter and I know how, but I don't know what is the second power of Cr? would you mind explain what that means and how can I do that, please?
Thank you

You can use Haar-based face detection from Accord.NET, which is extension to AForge.NET.
