A Reconfigurable VLSI Structure for DWT

DWT has been the main algorithm of image compression, such as in JPEG2000.This paper propose a VLSI structure to perform line-based DWT using lifting scheme. We use this mean to achieve 1D and 2D DWT, examination results show this structure is simple and efficient.
