Unified metric for digital video processing (umdvp)

摘要

The present application develops a unified metric for digital video processing (UMDVP) to control video processing algorithms. The UMDVP metric is defined based on coding information of MPEG encoded video for each pixel in a frame. The definition of the UMDVP metric includes local spatial features. The UMDVP metric can be used to control enhancement algorithms to determine how much a pixel can be enhanced without boosting coding artifacts. It can also be used to instruct artifact reduction algorithms where and how much reduction operations are needed.
