摘要

闪烁是预测视频编码中最恼人的时间伪影之一。当编码器为了节省数据速率而被迫跳过宏块时，它会经常出现，特别是在缓慢移动的低纹理对象中。推导了一个非常简单的无参考度量，用于自动检测由这种宏块跳变引起的时间闪烁伪影。对不同的H.264编码视频序列进行了测试。

Measuring of Flickering Artifacts in Predictive Coded Video Sequences

Flickering is one of the most annoying temporal artifacts in predictive video coding. It will frequently appear in particular within slow moving low textured objects when the encoder is forced to skip macroblocks in order to save data rate. A very simple no-reference metric is derived for automatic detection of temporal flickering artifacts resulting from such macroblock skipping. Tests are performed for different H.264 encoded video sequences.
