Solutions for Face recognition without using neural network?

Question

what is the problem for which neural network is a solution .what is the technique adopted for image processing before invention of neural network.is neural network just a way of programming where processor can be made to learn to solve the process.will neural network get trained even during the testing.can face recognition be done by storing a database of pictures and comparing the test face based on pixel by pixel information with the stored database of faces.what are the ways of implementing face recognition without using neural networks.

Answer 1

- The very important reason to move towards Neural Network rather than pure Image Processing algorithms may rely on their error and variation tolerance.

- Neural Networks easily adopt to the environment while pure mathematics in image processing is rigid.

- Sometimes formulating a phenomenon is too difficult or even impossible, while Neural Networks do the Rule(Information) Extraction automatically.

Q. what is the technique adopted for image processing before invention of neural network?

A. You can't call a single method adopted. You should know that before inventing Neural Networks, people had many difficulties in their pattern recognition. That was mostly because they had to invent a new way of processing for every case they encountered.

Q.will neural network get trained even during the testing ?

A. In Backpropagation, it depends on the way you implement it. While in those which are on unsupervised techiniques, there is actually no testing; whatever you show the network goes for learning.

Q.can face recognition be done by storing a database of pictures and comparing the test face based on pixel by pixel information with the stored database of faces?

A. Sure. That's the way a BPNN works.

I refer you to the following link, if you want to use a BPNN, for training, testing, recognition, etc. :

1) go to http://www.MehranHoodeh.com

2) Click on "Experiences"

3) Click on "Neural Networks"

4) Download "MPE".

5) Extract the compressed file.

6) Run "MPE.exe"

7) Go to "Help -> Offline Help" menu option.

8) Have a read through its documents.

9) Run samples. (Start with XOR)
