A rescheduling and fast pipeline VLSI architecture for lifting-based discrete wavelet transform
In this paper, we propose a fast pipeline VLSI architecture for 1D lifting-based discrete wavelet transform (DWT). This design method merges the filtering steps called the predict...

On the Dual-Tree Complex Wavelet Packet and M-Band Transforms
The two-band discrete wavelet transform (DWT) provides an octave-band analysis in the frequency domain, but this might not be "optimal" for a given signal. The discrete w...

Process variation tolerant low power DCT architecture
: 2-D Discrete Cosine Transform (DCT) is widely used as the core of digital image and video compression. In this paper, we present a novel DCT architecture that allows aggressive v...

A directional, shift insensitive, low-redundancy, wavelet transform
Shift variance and poor directional selectivity, two major disadvantages of the discrete wavelet transform, have previously been circumvented either by using highly redundant, non...

Improving the memory behavior of vertical filtering in the discrete wavelet transform
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...
