【摘要】 针对P帧,提出一种基于时域和空域联合的帧内预测模式快速判别算法。该方法由时域和空域的相关性分别得到一个最可能帧内预测模式,基于一定的准则缩小待选模式个数,避免了不必要的RDO计算。更多还原

【Abstract】 Aimed at P frames, a new fast intra prediction algorithm, based on the joint of temporal and spatial correlation, is proposed. Exploiting the temporal and spatial correlation, two most probable prediction mode can be obtained. With some special rules, the prediction modes can be reduced, and much unnecessary RDO computation is avoided.更多还原
