In translation theory and practice , translator is in a subordinate position and simply regarded as a bilingual agent who decodes messages in the source language and re - encodes messages in the target language 摘要在翻譯理論和實踐中譯者一直被置于一種從屬的地位,其角色被簡單地定位為原文與譯文之間的轉(zhuǎn)換者。
Firstly , based on conventional vq , a fast algorithm named equal - sum block - extending nearest neighbor search ( ebnns ) is presented , which not only can achieve the reconstructed image of full search algorithm but also can greatly reduce both the codeword search ratio and chip area . in order to improve coding efficiency , a new algorithm called correlation - inheritance coding is proposed , which is embedded in conventional vq system to improve compression ratio by re - encoding the indexes 首先,在普通矢量量化基礎(chǔ)上提出了等和值塊擴展最近鄰快速碼字搜索算法( ebnns ) ,該算法在圖像畫質(zhì)達到窮盡搜索算法的前提下,大大降低了碼字搜索率和硬件實現(xiàn)面積;為了提高編碼效率,在相關(guān)性編碼方面,提出了相關(guān)繼承編碼算法,對普通矢量量化后的編碼索引進行無損重編碼。
