Abstract: Images contain large amounts of information that requires much storage space, large transmission bandwidths and long transmission times. Therefore it is advantageous to compress the image by storing only the essential information needed to reconstruct the image. Discrete Wavelet Transform (DWT) is most popular transformation technique adopted for image compression In this work” LIFTING BASED-DWT” technique is proposed and is implemented on FPGA Instead of using ROM as a cache memory we are using FIFO as an storage device by which throughput can be increased.
Keywords: Image compression, FIFO, Xilinx, lifting base DWT.
