context n. 1.上下文;文章的前后關(guān)系[脈絡(luò)]。 2.(事情等的)關(guān)節(jié),范圍,場合,處境,條件;來龍去脈。 tell the meaning of a word from its context從一個字的上文下推知其字義。 in one context 在一定場合,在某一范圍內(nèi)。 in the context of 在…情況下。 in this context 關(guān)于這一點(diǎn),在這種場合下。 outside the context of 在…之外。
We study the context modeling in lossless image compression 研究了無損圖像壓縮中的context模型設(shè)計(jì)問題。
context modeling is a key point in compression algorithm designing context模型是無損壓縮算法設(shè)計(jì)中關(guān)鍵部分,它對算法壓縮性能至關(guān)重要。
This algorithm is composed of the predictor and rice coding based on context modeling 該算法設(shè)計(jì)了專門的預(yù)測器和基于上下文建模的rice編碼。
Below we elaborate personal networking related issues in internet protocols, context modelling, and configuration management 下面,我們展開個人網(wǎng)絡(luò)相關(guān)的,在互聯(lián)網(wǎng)協(xié)議,環(huán)境建模和配置管理方面的議題。
In this second part of personal networking challenges i will address three key enablers : internet protocols, context modelling and configuration management 在個人網(wǎng)絡(luò)挑戰(zhàn)的第二部分,我將解決三個關(guān)鍵使能因素:互聯(lián)網(wǎng)協(xié)議,環(huán)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 ) 在漢語句法分析和語義分析的基礎(chǔ)之上,本文建立了漢語上下文語境模型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編碼方法的啟發(fā),本文提出了一種新的用于圖像壓縮的小波系數(shù)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 本文首先介紹了相關(guān)標(biāo)準(zhǔn)及所使用的context模型,然后對連續(xù)色調(diào)??即灰度和彩色圖像無損壓縮中常用的context模型進(jìn)行了分析討論。
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的高概率出現(xiàn),使得第二位平面具有很大的相關(guān)性,因此文中算術(shù)編碼的上下文模型的設(shè)計(jì)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 針對這種情況,本文引入exp-golomb碼來減少較大的變換系數(shù)二值化的冗余問題,提出了一種unary碼和exp-golomb碼相結(jié)合的的二進(jìn)制化算法,該算法避免了設(shè)立標(biāo)志位所帶來的附加損耗,分別針對于變換系數(shù)中的luma系數(shù)和chroma系數(shù)的概率分布特點(diǎn),采取了不同的自適應(yīng)切換設(shè)置,并且相應(yīng)地增加了概率模型。
