Measuring of Flickering Artifacts in Predictive Coded Video Sequences

Abstract

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.
