幀滑動 的英文怎麼說
中文拼音 [zhènggǔdòng]
幀滑動
英文
frame slip-
Smooth animation. we can derive intermediate frames by using spherical interpolation
我們可以使用球性插值得到中間幀，以實現平滑的動畫。Compensation method of motion among the frames is also an important factor to affect the stability of image sequence, if the image sequence is compensated directly with the acquired movement vectors, it will feel the jumping of frame. in the paper, the parameter to compensate for the current image can be determined by average value filtering and have been applied to given motion model to stabilize the image stream. it can realize smoothly processing the image sequences to assure its stabilization
由於幀間運動的補償方法是影響圖像序列平穩性的一個重要因素，直接用運動矢量進行補償，將會使圖像產生跳躍感，本文提出採用均值濾波的方法來確定各幀的補償量，實現了圖像序列的幀間平滑銜接，提高了動態圖像序列的平穩性。An error detecting method which can prevent the decoding error affecting the next video packet head is used, and a restoration measure for b frame based on the mv prediction which can improve the visual quality has been studied. 3. a novel marking algorithm for ip diffserv based on the transmission condition and the different importance of video streams for decoder has been introduced
2實現了mpeg - 4的差錯檢測、可逆變長解碼rvld和差錯掩蓋方法:對i或p幀紋理區的差錯先用rvld進行解碼，然後對殘留的差錯用空間插值或運動補償方法進行掩蓋，而對p幀的運動矢量mv ，利用圖像的空間平滑特性進行恢復; 3針對b幀差錯的復原，我們還提出了一種基於運動估計的方法。Compared with conventional tracking methods, the detector is a stronger observation model due to its discriminative power gained by training over large data sets, which makes it more adaptive to image changes ; meanwhile, this built - in detector also equips the tracking framework with auto - initialization and the ability to quickly discover new targets
另一方面，與逐幀檢測相比，基於檢測的跟蹤利用了物體運動在時序上的連續性，因此速度更快；且由於時序上檢測信息的融合使輸出更平滑，降低了誤報和漏檢。Experiments prove that the system can be used to segment and track the single moving rigid object with comparatively large inter - frame vector, and the result is good enough especially to those objects with smooth contours
實驗證明，本方案對于幀間位移較為明顯的單個平移運動剛體，特別是外部輪廓較為平滑的物體具有良好的分割與跟蹤效果。The following algorithms are proposed : 1. an algorithm of shot segmentation is proposed. firstly, the data in each frame is quantized in hsv model ; then based on histogram of each frame, the difference of adjacent frames, the difference of cumulate frames and the percentage of the frame difference in a defined window are computed ; furthermore, the adaptive average in a window, the adaptive thresholds and sliding windows are obtained
具體內容為: 1 .在鏡頭分割中，首先將視頻幀數據在hsv顏色空間下進行量化降維，隨后依據直方圖的統計特性，計算連續幀差值，累加幀差值及窗口幀差比，並以此確定自適應窗口均值、多個動態閾值及滑動窗口進行突變鏡頭和漸變境頭分割。分享友人
