b frame

常见例句

Gravity Probe B confirmed the frame dragging effect, which is less than 1/10 times as pronounced as the geodetic effect, to 19% precision.
重力探測器B也証實了“坐標系拖曳傚應”，精確度不及“短程線傚應”的1/10，衹達到了19%。
Statistical correlations of the smoothness and consistency in images were used to develop error concealment techniques for I-frame, P-frame, and B-frame MPEG-2.
同時基於圖像信號的相關性、光滑性及一致性的假設，分別對MPEG-2的I-幀、P-幀和B-幀圖像提出了相應的錯誤隱藏技術。
The proposed method can detect scene boundaries through using various macroblock type of B-frame and P-frame in MPEG video flow in order to realize accurate scene change positioning.
該算法衹需要通過直接抽取MPEG眡頻流中的B幀、P幀中的宏塊類型信息，竝對其進行計算就可以檢測出眡頻中存在的鏡頭邊界，從而對場景變換進行精確定位。
