  • 移動補償畫面內插法,主要應用於畫面更新率的提升和降低所需傳送的影像資料以達到符合傳送的頻寬。針對降低所需傳送的影像資料,我們常在編碼端先將影像做畫面跳張後,再進行編碼,最後在解碼端利用移動補償畫面內插法將畫面插值回來。因為在解碼端並無原始欲作畫面跳張的畫面資訊,所以重建畫面的畫面品質並沒有很好。有鑑於此,本篇論文提出了『先進移動補償畫面內插法』,簡稱AMCFI。我們將原本在解碼端為了解決插值畫面所發生的視覺效應而做的處理,像是移動向量的重新安排和權重式移動補償,移至編碼端,並藉著參考這些欲作畫面跳張的原始畫面資訊,使重建畫面的畫面品質為最佳的。又因為使用先進移動補償畫面內插法可節省原本的編碼時間,所以在本篇論文的最後,我們將針對編碼時間提出了兩個先進影像編碼技術來做探討。


    Motion compensated frame interpolation (MCFI), it mainly used in frame rate up-conversion and video compression. In order to transmit a huge amount of video data over the bandwidth-limited channels, we often do frame skipping in the encoder and use MCFI to interpolate the frame in the decoder. But the quality of interpolated frame is not good, because we don’t have the original skipped frame information in the decoder. So we propose the advanced motion compensated frame interpolation (AMCFI) to improve the problem. In the encoder, we improve the quality of interpolated frame by using the original skipped frame information to do some processes such as motion vector refinement and weighted motion compensation which are used to solve the interpolated frame’s visual effect in the decoder. We also can find that AMCFI reduce coding time in the encoder, so we will propose two advanced video coding technics to reduce coding time.
