Hello,

I am working with face recognition. I have two models from two separate datasets with the same number of dimensions.

I wish to implement this method to combine PCA models.

My linear algebra isn't great. So i am lost after step 1 for section 3.1.

I can appreciate how to get the combined mean, but from that point on wards, it's a bit over my head.

Anyone here literate in this symbolic medium of communication?
