Find basis images and represent image X with basis images. X = AH Y A  (separable) => x(m,n) = \uf053k \uf053l a (k,m)a (l,n) y(k,l) Represent X with NxN basis images weighted by coeff. Y. Obtain basis image { a (k0 ,m)a (l0 ,n) }m,n by setting Y={\uf064(k-k0, l-l0)} & getting X. In matrix form A k,l = a k al T ~ a k is kth column vector of A T (akT is kth row vector of A) Transform coeff. y(k,l) is the inner product of A k,l with the image.
