Abstract: Discrete wavelet transformation(DWT) has become very popular as the basis of many recent image processing and compression techniques and has been adopted by new image compression standard, i.e., JPEG2000. 5/3 wavelet transformation is mainly used for lossless image compression in JPEG2000. This paper presents a novel hardware structure and implements it in FPGA hardware.
