Unformatted text preview: aces, reveals eigenfaces as the optimal basis for representing
images. We saw it was not good for representing other images (e.g. the dog).
What about all natural images – Do we expect to get a savings?
(In other words, do natural images occupy the full pixel space or do they lie on a
lower dimensional subspace?)
A) Yes I think Natural images lie in a lower dimensional subspace
B) No I think Natural images ﬁll the full pixel space
There are many redundancies in natural images (nearby pixels are highly correlated
and pixels along an edge are highly correlated over long ranges) 9...
