Fisherfaces components and regions [closed]

edit

Hi,

I want to use face recognition using the different regions (or components) that the Fisherfaces identify. For example, some regions or components of a Fisherface may describe the eyes. I want to compare against the same regions of other Fisherfaces. I mean, try to recognize who has eyes similar to mine for example.

I know here in this post (http://bytefish.de/blog/fisherfaces/) there are some example using celebrities. They try to determine which celebrity you resemble the most.

I want to know how to get the Fisherfaces components and how to interpret them (as the author of this post [http://bytefish.de/blog/fisherfaces/] does in the plots he made).

Any help is welcomed. Thank you very much!
