We describe the use of the discrete wavelet transform (DWT) for non-parametric linear time-invariant system identification. Identification is achieved by using a test excitation t...
—The 2D Discrete Wavelet Transform (DWT) is a time-consuming kernel in many multimedia applications such as JPEG2000 and MPEG-4. The 2D DWT consists of horizontal filtering alon...
The discrete wavelet transform (DWT) is used in several image and video compression standards, in particular JPEG2000. A 2D DWT consists of horizontal filtering along the rows fo...

In this paper, we present a VLSI architecture for separable 2-D Discrete Wavelet Transform (DWT). Based on 1-D DWT Recursive Pyramid Algorithm (RPA), a complete 2-D DWT output sch...
