I have large face database and I want to search through it, for example I put new face image and system return me best N similarities. I know that PCA,LDA,procrustes analysis are used for this, but it seems that I need to project all large database to PCA space(I don't know any library that can handle that).

maybe there are some tools,software,library for this?

any advices appreciated.
