rate distortion model

基本解釋

We then present a simple but effective rate-distortion model for video transcoder.
接下來(lái)，本文提出了一種初步但有效的轉(zhuǎn)碼率失真模型。
Generally, the rate distortion model is employed to compute quantization parameter for the controlling bit rate.
通常碼率控制算法使用一定的率失真模型來(lái)決策量化參數(shù)從而控制碼率。
The multi-resolution motion estimation scheme and an efficient rate-distortion model are adopted with early termination rules to accelerate the search process.
此算法基于多分辨率運(yùn)動(dòng)估計(jì)方案和新率失真模型進(jìn)行預(yù)測(cè)模式快速選擇，并結(jié)合帶提前退出準(zhǔn)則的快速搜索算法來(lái)加速搜索過程。
