Description: Quincunx wavelet transforms
Quincunx wavelets are non-separable transform that allows to avoid using vertical/horizontal wavelets. The scaling grows like 2^{j/2} with the scale j instead of 2^j, which can be advantageous.
Biorthogonal quincunx wavelets are implemented using a simple wrapper to the code of Dimitri Van De Ville.
Redundant, translation invariant transform are implemented with the lifting scheme. Platform: |

Description: JPEG2000标准 图形压缩算法与集成电路架构-This book consists of 10 chapters.
The first two chapters provide an
overview of the principles and theory of data and image compression with numerous examples. In Chapter 3, we review the current JPEG still standard for image compression, discuss the advantages and disadvantages of current JPEG, and the need for the new JPEG2000 standard for still image com-
pression. We discuss the principles of discrete wavelet transformation and its implementation using both the convolution approach and the lifting approach in Chapter 4. In this chapter, we discuss the theory of multiresolution analysis and also the principles of lifting factorization for efficient implementation of discrete wavelet transform. In Chapter 5, we discuss VLSI algorithms
and architectures for implementation of discrete wavelet transform and review different architectures for lifting-based implementation. In Chapters 6 to 8, we concentra Platform: |
