We study the context modeling in lossless image compression 研究了无损图像压缩中的context模型设计问题。
context modeling is a key point in compression algorithm designing context模型是无损压缩算法设计中关键部分,它对算法压缩性能至关重要。
This algorithm is composed of the predictor and rice coding based on context modeling 该算法设计了专门的预测器和基于上下文建模的rice编码。
Below we elaborate personal networking related issues in internet protocols, context modelling, and configuration management 下面,我们展开个人网络相关的,在互联网协议,环境建模和配置管理方面的议题。
In this second part of personal networking challenges i will address three key enablers : internet protocols, context modelling and configuration management 在个人网络挑战的第二部分,我将解决三个关键使能因素:互联网协议,环境建模和配置管理。
On the basis of chinese syntactic analysis and semantic analysis, we construct a model of chinese context, called chinese context model ( ccm ) 在汉语句法分析和语义分析的基础之上,本文建立了汉语上下文语境模型ccm(chinesecontextmodel,ccm)。
Inspired by glicbawls, calic, ececow, and ezw coding schemes, a new context model of wavelet coefficients for image compression is proposed 受glicbawls、calic、ececow和ezw编码方法的启发,本文提出了一种新的用于图像压缩的小波系数的上下文模型(pcw)。
We analysis and make comparison among several frequently adopted context models in lossless compression algorithm for image . image compression framework based on integral wavelet is proposed and implemented 本文首先介绍了相关标准及所使用的context模型,然后对连续色调??即灰度和彩色图像无损压缩中常用的context模型进行了分析讨论。
So there ’ s a great correlation among the second bitplane . so we offered a new arithmetic coding scheme in which the design of context models is based on level and bitplane . considering the difference between luma and chroma coefficients, we will make it separately 由于abslevel=1的高概率出现,使得第二位平面具有很大的相关性,因此文中算术编码的上下文模型的设计方案主要基于level值和bitplane。
This paper presents a algorithm that combined unary code and exp-golomb code . it switched separately in consideration of the difference between luma and chroma coefficients, instead of setting a marking bit which will bing loss at the same time, and also added some corresponding context models . it had been tested on sd, hd and cif, three types of sequence, and the bitrate had been saved by 1.24134 %, 0.10016 % and 0.16029 % on average 针对这种情况,本文引入exp-golomb码来减少较大的变换系数二值化的冗余问题,提出了一种unary码和exp-golomb码相结合的的二进制化算法,该算法避免了设立标志位所带来的附加损耗,分别针对于变换系数中的luma系数和chroma系数的概率分布特点,采取了不同的自适应切换设置,并且相应地增加了概率模型。
