Video signal extrapolation executing method for use in video processing application, involves estimating error and/or predetermined signal values based on previous signal values, and replacing previous signal values by estimated values

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a method and device for improving video processing by estimating and replacing certain signal values—such as errors or missing information—in three-dimensional video signals. The method uses previous signal values to estimate better signal values, helping to create a more accurate or complete video representation. A dedicated device with a processing unit can execute this extrapolation process.

Patent Abstract

The method involves providing signal values, which represent the three-dimensional information. The error and/or predetermined signal values are estimated based on the former signal values, and the former signal values are replaced by the estimated values. The three dimensional signal values are taken for the estimation. The signal value is represented with a three-dimensional parametric model. An independent claim is also included for a device for executing the signal extrapolation, comprising a processing unit.
