| http://www.w3.org/ns/prov#value | - The action of the DCT (and its inverse, the IDCT) can be described in terms of a transform matrix A. The forward DCT (FDCT) of an N ?? N sample block is given by: Y = AXAT eqn 1.1 And inverse DCT (IDCT) X = ATYA eqn 1.2 where X is a matrix of samples(macroblock), Y is a matrix of DCT coefficients and A is an N ?? N transform matrix.
