研究H.264的编码模式选择方案,根据视频序列的时域相关性和空域相关性的关系,模式选择包括帧内预测和帧间预测,帧间预测基于率失真函数,在一帧图像的编码中则可以采用提前终止预测方向的方法降低编码器端的复杂度。 According to the relationship between temporal correlation and spatial correlation of video sequences, the mode selection includes intra prediction and inter prediction, and the inter prediction is based on the rate distortion function, and the encoding of a frame of image You can reduce the encoder-side complexity by prematurely ending the prediction direction.
