Image coder based on residue number system for progressivetransmission
Anna Tatsaki, Thanos Stouraitis, C. Goutis · Electronics Letters · 1995
A computationally efficient algorithm for image compression and progressive transmission is presented. A prime-factor discrete cosine transform (DCT) is applied, where the coefficients are computed in three groups and are residue represented by a different bit allocation. A novel lattice vector quantiser is used for the quantisation of each group.
