false zero method 中文意思是什麼
false zero method
解釋
虛零法-
Generally speaking, a coding algorithm must be low complexity and work at high speed. in this paper, the coding methods are studied to increase coding speed. firstly, a novel method based on temporal prediction to detect all - zero dct coefficients is proposed, which can greatly reduce the coding cost and maintain a good tradeoff between correct detecting ratio and false detecting ratio with little additional computation
本文以h . 263壓縮編碼標準為基本框架,針對其中影響壓縮效率和速度的瓶頸展開研究,包括快速運動搜索演算法的研究、預判零方法的研究以及mmx技術在視頻編碼中的應用等,提出了一種基於時域預測的預判零新方法,在不影響重建視頻質量的條件下具有較高的判別效率,節約了大量dct變換和量化的時間,提高了編碼的速度,達到了實時性要求。
