摘要：
In this paper, we have introduced a generalized block-lifting structure using the 2-D CORDIC algorithm as a block of 4-band linear phase paraunitary filter banks (LP PUFB) based on the quaternionic algebra (Q-PUFB) for the lossy-to-lossless image coding. A bank Q-PUFB based on the 2-D CORDIC block-lifting structure reduces the number of rounding operations and has a regular layout. Since the block-lifting structures with rounding operations can implement the integer-to-integer transform (Q-PUFB). The parallel-pipelined efficient architecture ((PE)-E-2_Q-PUFB) has been proposed. The low latency separable image processing is implemented in the given architecture.
