模式選取在H.264的編碼程序中由於它的時間複雜度是一個瓶頸。在本文中,我們提出了一種新的方法來將框間模式選取的測試次數由原來的七次降為三次。詳細地,我們辨認最小的兩個框間模式的輕量成本,並檢查它們的相鄰與否,來決定保留或捨棄一些模式。我們還平行化一部分的程式碼來加快執行時間。實驗結果證明,無論何種視訊類型的情況,所提出的方法在執行時間方面改進了效能,並仍保持幾乎相同的視訊品質與幾乎沒有改變的編碼視訊大小。
Mode decision at the encoder processing of H.264 is a bottleneck due to its time complexity. In this paper, we propose a new method to reduce the original 7 inter modes to 3. In particular, we identify the smallest 2 light-weight costs of inter modes, and check if they are neighbors or not, to determine whether to save or discard some of the modes. We also parallelize a part of the code to speed up the executing time. The experimental results demonstrate that the proposed methods improve the performance in terms of executing time, regardless of the video types in consideration, and still keep almost the same video quality with almost no change in encoded video size.
