Wavelet transform coding has been drawing much attention because of its ability to decompose images into a hierarchical structure that is suitable for adaptive processing in the transform domain. This paper presents an Efficient VLSI design of one-dimensional direct discrete wavelet transform processor. The proposed architecture computes three DWT stages and uses four parallel filters. The architecture...
This paper presents a VLSI implementation of One Dimensional Direct Discrete Wavelet transform (1-D DWT). The DDWT can be viewed as a multi-resolution decomposition of a signal. This means that it decomposes a signal into its components in different frequency bands (octave bands). We propose a new architecture using parallel filters. We consider the implementation of 1-D three levels DWT. The proposed...
