摘要

离散小波变换是当今许多图像处理和压缩技术的基础

并被最新的ISO/IEC静态图像压缩标准JPEG2000所采用.基于提升方法的离散小波变换比传统的基于卷积的运算量小.我们为JPEG2000中的小波提升算法提出一个硬件结构

该结构整体运算速度高

存储需求低

硬件资源耗费少.我们提出在数据通道之外实现边界扩展

以降低数据通道的复杂性

提高运算效率.我们通过采用流水线技术

进一步提高了硬件设计的运算效率.

Abstract

Discrete Wavelet Transform(DWT) has become very popular as the basis of many recent image processing and compression techniques and has been adopted by new image compression standard

i.e.

JPEG2000.The conventional convolution based DWT is computationally intensive.Such drawbacks can be overcome by using the lifting based scheme for the DWT.We presented a novel hardware structure for lifting based wavelet transform in JPEG2000.The hardware structure improves memory/speed tradeoff.Its computation speed is high and memory requirement is low.The complexity of datapath is reduced and the efficency of the system is improved by implementing the function of edge extension outside of data path.In the datapath design

we used pipeline technique to further improve the efficiency of the design.
