International conference on Graphic and image processing (ICGIP)
作者: Gholipour, Morteza Noubari, Hossein Ahmadi Kamarei, Mahmoud Univ Tehran ECE Dept Tehran Iran Univ British Columbia Vancouver BC Canada
Discrete wavelet Transform (DWT) is widely used in signal processing applications. In this paper, we describe hardware implementation of a lifting-based DWT, which is used in image compression. The CDF(2,2) lifting-ba... 详细信息
