Application Map in the Noise Suppression Filter for Video Compression

Abstract

This paper considers an application map method usage together with the Nose Suppression Filter (NSF) in-loop filter for video compression. The application map method is described in details and simulations results of basic NSF are provided as well as simulation results of NSF powered with the application map method. It is demonstrated that the application map method allows to significantly improve objective performance results of basic NSF and additionally decrease decoder average complexity. As a result, an average bd-rate saving of NSF with the application map reaches 2.6% for luma component in Low Delay P coding configuration in comparing to Versatile Video Coding reference implementation (VTM) version 1.0.
