摘要
在我国最新的第二代数字音视频编解码算法标准（AVS2）的基础上，提出了一种多色度格式级联编码（MCFCC）的全色度（4:4:4采样格式）图像编码算法。MCFCC算法首先对4:4:4采样格式的图像进行色度下采样转换成4:2:0采样格式的图像，然后进行4:2:0采样格式的帧内预测、变换、量化、反量化、反变换、熵编码和在率—失真最优化过程中使用带权重的4:4:4采样格式的失真计算方案，最后将其上采样为4:4:4采样格式的预测补偿图像并采用4:4:4采样格式的环内滤波补偿算法。实验结果表明：对于全色度自然图像，MCFCC算法在低编码复杂度和低实现成本（完全复用4:2:0编解码模块）的前提下，综合编码效率进一步提高。
Abstract
In the second generation of audio video coding standard (AVS2)
a multi-chroma format cascaded coding method (MCFCC) for full-chroma (4:4:4 sampling format) images coding was proposed.The MCFCC algorithm firstly converts the 4:4:4 sampling format image into 4:2:0 sampling format image
then the 4:2:0 sampling format image was processed by 4:2:0 sampling format intra prediction
transform
quantization
inverse quantization
inverse transform
entropy coding and a weighted 4:4:4 sampling format distortion calculation method in the rate-distortion optimization process
finally 4:4:4 sampling format in-loop filtering and offset algorithms were applied to the 4:4:4 sampling format image after up sampling.The experimental results show that
for full-chroma natural images
the MCFCC algorithm achieves higher coding efficiency at very low additional encoding complexity and very low additional design and implementation cost.
