Method, Apparatus, and Computer Software for Modifying Moving Images Via Motion Compensation Vectors, Degrain/Denoise, and Superresolution

Abstract

A video processing method and concomitant computer software stored on a computer-readable medium comprising receiving a video stream comprising a plurality of frames, removing via one or more GPU operations a plurality of artifacts from the video stream, outputting the video stream with the removed artifacts, and tracking artifacts between an adjacent subset of the plurality of frames prior to the removing step.

AI Technical Summary

Benefits of technology

[0011]The present invention is of a video processing method and concomitant computer software stored on a computer-readable medium, comprising: receiving a video stream comprising a plurality of frames; removing via one or more GPU operations a plurality of artifacts from the video stream; outputting the video stream with the removed artifacts; and tracking artifacts between an adjacent subset of the plurality of frames prior to the removing step. In the preferred embodiment, tracking comprises computing motion vectors for the tracked artifacts, including computing motion vectors for the tracked artifacts with at least a primary vector field and a secondary vector field with double the resolution of the primary vector field, computing motion vectors for the tracked artifacts via subpixel interpolation without favoring integer pixel lengths, and/or computing motion vectors for the tracked artifacts with a

Problems solved by technology

The need and desire to make video, particularly that converted from stock footage on traditional film, look less grainy and noisy is a considerable challenge due to high transfer costs and limitations of available technologies that are not only time consuming, but provide poor results.
