semantic coding 中文意思是什麼
-
Traditional coding algorithms are based on simple n - gram models. those distant constraints and some redundancies in natural language, such as word order redundancies, semantic redundancies and syntactic redundancies, are neglected in the n - gram models. in order to find and reduce those redundancies, we need more intelligent algorithms based on more effective models
通用無損數據編碼是數據壓縮領域的一個重要的分支，現有的無損數據編碼方法大多是基於n - gram模型的， n - gram模型忽略了自然語言中的遠距離約束和諸如詞序冗餘、語義冗餘、句法冗餘等冗餘，為了找出並減少這些冗餘，需要更有效的語言模型和更智能的演算法。 -
This bug occurs when stored data fails to satisfy certain syntactic or semantic constraints ; when software crashes due to an error, not in the coding, but in the data the code is manipulating
這種錯誤在已存儲的數據不能滿足某些句法或語義約束時發生；此時軟體會因為代碼操縱的數據中的錯誤而不是編碼中的錯誤而崩潰。 -
Audio - video object - based coding and description are the distinct features of mpeg - 4 standard. in the mpeg - 4 standard, video frame was composed of a series of independent semantic video object, which was encoded independently
在mpeg - 4標準中，視頻幀被認為是由一系列相互獨立的運動對象組成，視頻幀的編碼也直接針對一個個視頻對象。 -
However, no general method to video motional object segmentation is accepted and presently, scenes can be divided into many semantic objects and coded by content - based representation and scalability that will be playing an important role in 2g technologies of video coding and segmentation
目前較為流行的分割方案大多依賴于視頻圖像的某一種或幾種屬性進行分割，並且較多的是在像素塊基礎上的，需要預先設定門限值，因此分割精度不高，圖像邊緣也較為粗糙。
