Without exploiting motion information , normal 3d wavelet transformation can decline its coding efficiency in complex and movable scene 常規(guī)的三維小波變換因為沒有利用運動信息,對復雜的運動場景的編碼效率會大幅度下降。
C2dvlc employs context - based adaptive multiple table coding to exploit the statistical correlation between dct coefficients of one block for higher coding efficiency 算術編碼利用編碼符號的聯(lián)合概率,并且其機制更易于概率匹配,因此編碼效率高。
The three options can improve coding efficiency , but they also enhance the complexity of operation of encoder , so they affect the real time operation of encoder 這些可選模式的選用提高了編碼性能,但同時也增加了運算的復雜度,影響了編碼的實時性。
When the frame field adaptation is applied on the picture level , the coding efficiency is improved greatly , compared with the pure frame coding or the pure field coding 與沒有幀場自適應的幀編碼或者場編碼相比,當在圖像級使用幀場自適應技術時,編碼效率得到很大提高。
The software programmed by c language composing of a modular structure is beneficial for reducing the volume of software as well as improving code efficiency and operational reliability 系統(tǒng)軟件用c編寫,采用模塊化結構,在減小軟件體積,提高代碼效率和運行可靠性方面都有了保證。
