A block-based subband image coder that exploits the ability to perform decimation in the discrete cosine transform (DCT) domain to effect a pyramidal data structure is described. The proposed “DCT pyramid” has a distinct feature of improved image rendition properties without the associated blocking artifacts at low bit-rates
