摘要
详细分析了 H .2 64视频编码标准中的整数变换和量化过程。 H .2 64采用 4× 4整数变换 ,并将尺度调整融合在量化过程中 ,降低变换算法复杂度和减少乘法次数 。
The theory of transform and quantization in H 264 is analyzed in detail The complexity of transform is lower by using a 4×4 integer transform, which is derived from DCT transform A scaling multiplication is integrated into the quantization to reduce the total number of multiplications, which makes H 264 an effective video coding standard
