Abstract:
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: 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, and wherein a three dimensional noise reducer (3DNR) process precedes an adaptive detail reducer (ADR) process, and wherein the 3DNR performs three dimensional noise reduction on the original picture in two spatial dimensions and a temporal dimension, and the ADR process performs adaptive detail reduction on the original picture on selected difficult-to-track details.
