Lifting Based-Dwt Compression Technique Using Fpga

Image compression is one of the major image processing techniques that is widely used in medical, automotive, consumer and military applications. Discrete wavelet transforms is the most popular transformation technique adopted for image compression. Complexity of DWT is always high due to large number of arithmetic operations. A modified Distributive Arithmetic based DWT architecture is proposed and is implemented on FPGA.In this paper” LIFTING BASED-DWT” technique is proposed and is implemented on FPGA. Lifting Scheme entirely relies on spatial domain in this proposed method using LB-DWT area utilization is increased on the Vertex-5 FPGA kit. Instead of using ROM as a cache memory we are using FIFO as a storage device by which latency can be reduced and throughput can be increased.
