System for reducing noise in video processing

摘要

A system includes a data storage configured to store a model human visual system, an input module configured to receive an original picture in a video sequence and to receive a reference picture, and a processor. The processor is configured to create a pixel map of the original picture using the model human visual system. A first layer is determined from the pixel map. A weighting map is determined from a motion compensated difference between the original picture and the reference picture. A processed picture is then determined from the original picture using the weighting map and the first layer.

1. A system for reducing noise in video processing, the system comprising:
a data storage configured to store a model human visual system; an input module configured to receive an original picture in a video sequence and to receive a reference picture in the video sequence; a processor configured to:
create a pixel map of the original picture using the model human visual system;determine a first layer from the pixel map using the model human visual system;determine a motion compensated difference between the original picture and the reference picture,determine a weighting map from the motion compensated difference between the original picture and the reference picture, wherein the weighting map includes a value for each pixel based on a model of human temporal perceptibility; anddetermine a processed picture from the original picture by recombining the first layer with the weighting map, wherein the first layer goes beyond a noise layer that includes additive noise and is made up of a spatial detail layer including a value for each pixel based on a model of human spatial perceptibility.
