Abstract:

The usage of various prediction modes is the remarkable characteristic of H.264/AVC, however, it acquires heavy computation. Aiming at this problem, a fast mode decision algorithm is proposed for H.264/AVC encoding, which is on the basis of the application of all-zero blocks detection. By skipping some prediction modes after some comparisons, the algorithm can reduce the computational complexity of H.264/AVC encoding.

摘要： 多种预测模式的采用是H.264/AVC的特点，但带来了大量的计算。针对该问题，将全零块检测技术推广应用于H.264/AVC视频编码中对多种预测模式的快速选择，提出一种模式选择的快速算法。使用该算法，通过一些简单的比较等操作，就能跳过对某些预测模式的选择，减少了H.264/AVC视频编码器的运算复杂度。
