Anotace
Tato publikace uvádí nový algoritmus výpočtu 2D diskrétní vlnkové transformace (DWT) pomocí schématu lifting s použitím FPGA. Navržený postup je kompatibilní se standardem JPEG 2000.
Abstrakt
A novel approach to 2-D single-loop wavelet lifting with compatibility to JPEG 2000 is presented in this paper. A newly developed 2-D core of CDF 5/3 wavelet filter is presented that, using a new sequence of operations, simplify the design. Moreover, the proposed approach, that uses one pass for 2-D transform, directly produces final output and reduces significantly the need for storing intermediate results into memory. All the proposed structures can be efficiently pipelined in hardware. This paper describes the proposed approach, its implementation in FPGA, cost of such implementation, and brings an experimental evaluation as well as discussion of the features of the approach.
