Because the DCT uses cosine functions the resulting matrix depends on the horizontal
The key point is that all these “eigenvectors of cosines” come from simple and familiar matrices. Key words. cosine transform orthogonality
Is it possible to find an orthogonal transform matrix A that The Discrete Cosine Transform (DCT) / KLT Convergence for AR(1) Sources.
matrices are orthogonal (see e.g. [16] pp. 13 - 14; [17]). The discrete cosine transform of type II (DCT-II) with length ? is a linear mapping of IR? onto

of a symmetric "second difference" matrix. By varying the boundary conditions we get the established transforms DCT-1 through DCT-4.
