I saw the following animation at making sense of PCA , which shows blue data points.
I am reading a paper on Eigenfaces which says that:
"a typical image of size 256 by 256 becomes a vector of dimension 65536 or equivalently a point in 65536 dimensional space"
The paper is available at the following link: Eigenfaces for Recognition
My question is that in the context of Eigenfaces is each blue point an image?
Somebody please guide me.
