| 摘 要： | 在帧间预测编码过程中,为了选择最佳模式,H.264编码器对每种可能的模式进行计算,使用穷举搜索模式选择算法获取最佳模式,而穷举搜索的计算量非常大.根据图像采用的最佳编码模式与其内容的关系,利用图像序列的时/空相关性提出了一种H.264中帧间预测的快速预测模式选择法,改进了H.264时间效率、提高了实时性.

| Abstract: | In order to find the best mode in the process of inter-frame prediction encoding,H.264 encoder computes all possible block sizes.The best mode can be achieved by exhaustive search on all block sizes,however the computational complexity of this algorithm is extremely huge.According to the relationship between the best mode and its content,this article proposes a novel H.264 fast selecting inter-frame prediction mode algorithm by using temporal/spatial correlation of video sequence.It improves both the time e... |
