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
