本文提出了基于H.264标准的立体视频编码器方案,主要由预测(包括运动补偿预测和视差补偿预测)、变换和熵编码器三个部分组成。以左通道为主序列,右通道为辅序列。左通道采用简单的H.264编码,右通道以块为单位,进行运动补偿和视差补偿。通过实验证明了混合编码框架(运动补偿预测和视差补偿预测)具有更好的压缩效果,通过对不同图像复杂度的序列仿真实验,得到良好的重建图像质量,证明了本算法的有效性。
In this paper, a scheme of stereo video encoder based on H.264 is proposed, which is mainly composed of prediction (including motion compensation prediction and parallax compensation prediction), transform and entropy encoder. The left channel is the main sequence, the right channel is the auxiliary sequence. The left channel uses simple H.264 encoding, the right channel to block as a unit, for motion compensation and parallax compensation. Experiments show that the hybrid coding framework (motion compensation prediction and parallax compensation prediction) has better compression effect. By simulating experiments with different image complexity, good reconstructed image quality is proved, and the effectiveness of the proposed algorithm is proved.
