ADAPTIVE PRE-FILTERING BASED ON VIDEO COMPLEXITY AND OUTPUT BIT RATE

摘要

Approaches for dynamic pre-filtering of digital video based on video complexity and output bit rate. An adaptive video preprocessor determines a current video complexity of the digital video and an output bit rate. Thereafter, the adaptive video preprocessor dynamically updates the strength of one or more preprocessing filters based on the current video complexity and the output bit rate for the digital video. The adaptive video preprocessor may update the strength of a preprocessing filter based, at least in part, upon selected values of a video quality preference category. A video quality preference category may be assigned natural language values which may each be translated into a particular strength value for at least one of the one or more preprocessing filters.
