Level 4b - PART II - How does PCA Eigenfaces Recognize a Face? - The Algorithm Steps

April 19, 2012

1-Recap of Part 1 - What is PCA and what does it do?
2-Working Principles & Pre-requisites of PCA Eigenfaces
3-The Algorithm Steps of PCA Eigenfaces (animated & without messy mathematics )
*The steps to Train the Recognizer.
*The steps to Recognize an Unknown Face

What is PCA and what it does (Recap of Level 4b-Part I):
Before you learn the Algorithm steps in PCA to recognize a face, please you MUST know the following stuff:

We like your tutorials very much. Can you help us to provide sample code for recognizing face from database. We would like to compare captured image with image from database.


I very like your posts. I am looking for solutions to integrate face regconization into my product.
Thank you

Hi Mahvish, thx again for you tutorials, I am doing a simple login system with face recognition I have most of the code finished but would like to see you tutorials for some help on bits of the code that still don't work, do you think the tutorial for implementing face recognition will be up soon?

Again Thanks a LOT...


Thanks for nice tutorials !
When will you publish the next tutorial ? :)

I very like your tutorials !! You learned me a lot about PCA - Eigenfaces :)

Thanks a lot !

I've been looking for the face detection & recognition tutorials. Finally i found them here, they are very very helpful. Thankyou...
and also please post the "LEVEL-4C PART" as soon as possible.

Hi Mahvish,
Thanks for this helpfull tutorials. I'm new in EmguCv. My work is about face recognition. I need to save the eiganfaces images. Can you help me? I have trainingset images (frontal faces & all of them 100X100 piksels). List> trainingImages = new List>();
I load the images from a directory. And than how can I save the eiganfaces like in your 1st video (time 4:30, E1,E2...EK)
