  • 摘要: 新一代的高性能視頻編碼(HEVC)通過應(yīng)用各種先進技術(shù)來大幅提高視頻編碼的性能,然而,這些方法也大大增加了整個編碼過程,尤其是預(yù)測編碼階段的計算復(fù)雜度。該文提出一種應(yīng)用于高性能視頻編碼幀間預(yù)測的快速單元劃分算法。該算法基于HEVC靈活的四叉樹結(jié)構(gòu),根據(jù)被編碼單元的運動特性來確定所編碼信息的閾值,并以此作為單元劃分的提前終止條件,從而減少了不必要的單元劃分操作和率失真代價的相關(guān)計算,達到節(jié)省編碼時間和降低編碼復(fù)雜度的目的。實驗結(jié)果表明,在峰值信噪比(PSNR)損失僅為0.0418 dB的情況下,所提算法可以平均降低46.1%的編碼時間。
