Paper Abstract

We show how to improve the properties of a Hilbert space frame by projecting it onto a subspace of the Hilbert space. For example, for any frame on a n-dimensional Hilbert space, there is an orthogonal projection onto a subspace of dimension n/2 (if n is even) or (n+1)/2 (if n is odd) so that the projection of the frame becomes a tight frame.
