Abstract :
A new version of the discrete cosine transform (DCT) is introduced. The performance of this new version of the DCT for digital filtering and transform coding is compared to the old version of DCT [1] with various criteria; i.e., variance distribution, residual correlation, Wiener filtering, and maximum-reducible-bits.
