自動門限控制-
According to the complexity threshold, we auto - adaptatively adjust the qp. we use the smaller qp to quantify the more complicated macroblock and use the bigger qp to quantify the less complicated macroblok. the proposed algorithm can improve the h. 264 standard algorithm by a rate control algorithm on macroblock layer
在宏塊層利用了現有mad值表示宏塊復雜度,進一步根據宏塊的復雜度閾值自適應地調整量化參數qp ,對復雜度高的宏塊採用較小的qp值,進行精細量化;對復雜度低的qp值採用較大的qp值,以節約比特數。
