摘要
在JPEG2000编码系统的设计与实现过程中,EBOCOT的编码速度成为了整个系统设计的关键;为了有效的提高编码的效率,本文提出了一种基于零系数检测的通道并行算法,该算法利用小波子带变换后的特点,增加了对零码块和零条带的检测,减少了冗余扫描,并且实现多通道并行编码加快了编码速度。
In the design and implementation process of JPEG2000 coding system, EBOCOT encoding speed has become the key to the whole system design; in order to effectively improve the coding efifciency, this paper proposes a channel parallel algorithm based on zero coefifcients .This algorithm uses wavelet sub-after transformation with the characteristics, the detection of a zero increaseand zero code block strip, reducing redundant scanning and multi-channel parallel coded accelerate the encoding speed.
