dc.description.abstract | 區塊模式選擇是一種改善分散式視訊編碼的方法。由於有很多的因素會影響到區塊模式選擇,因此該如何選擇一個適當地區塊模式,並不是一件簡單的事。在這邊碩士論文當中,我們提出了一個低複雜度的區塊模式選擇,並且利用它可以更正確的選擇適當地區塊模式。我們提出的區塊模式選擇模組可以有效的改進執行效能,跟傳統的分散式視訊編碼比較的話,改進的程度大概可以到2.8dB。除此之外,另外一項貢獻就是在使用區塊模式選擇的分散式視訊編碼架構下,我們提出的自適應去區塊效應濾波器可以在維持客觀品質的前提下,使眼睛所看到的主觀品質有明顯有效的改進,這樣就不會使得影片看起來一格一格的。 | zh_TW |
dc.description.abstract | Block Mode Selection is one new way to improve the performance of distributed video coding (DVC). Since there are many factors influencing the correctness of Block Mode Selection, the decision of block mode is not an easy task. In this thesis, a low complexity Block Mode Selection model is proposed to select the block modes more correctly in the WZ frame. The proposed Block Mode Selection modules can increase the RD performance up to 2.8 dB as compared with the traditional DVC codecs. Moreover, the subjective quality can be improved by using the proposed adaptive deblocking filter, another contribution of this thesis, when the objective quality is kept the same. | en |
