Image Compression and the Discrete Cosine Transform Introduction
Because the DCT uses cosine functions the resulting matrix depends on the horizontal
The Discrete Cosine Transform
The key point is that all these “eigenvectors of cosines” come from simple and familiar matrices. Key words. cosine transform orthogonality
