How can I track detected objects from frame to frame
I want to track people's faces in a video stream (like a security camera), but I am running into a problem. I was using a Haar classifier to find the faces and sending the detected faces to a system ...

How does viola jones algorithm cope up with a test image size which is very different to training image sizes?
To my understanding Viola jones algorithm is a combination of weak classifiers built on training imageset. Lets say we have training images of 24x24 and algorithm selected 100 haar features and built ...

Face Classification. Is it OK to only use geometric features?
I am trying to teach myself the basics of facial recognition. I see that some resources use just distances between some points on the face (e.g., distance between 2 eyes, eyes to nose, etc). Some ...

How to store generated eigen faces for future face recognition?
My code works in the following manner:
1.First, it obtains several images from the training set
2.After loading these images, we find the normalized faces,mean face and perform several calculation.
