METHOD AND SYSTEM FOR GENERATING A HIGH-RESOLUTION VIDEO STREAM

摘要

A process for generating a high-resolution video stream, the process comprising: receiving (310) a low-resolution video stream; receiving (320) at least one high-resolution video stream; selecting (331) first image patches from said at least one high-resolution video stream; generating (332) respective first low-resolution counterparts of said first high-resolution image patches; storing (333) said first high-resolution image patches indexed by said first low- resolution counterparts in a first data storage; and improving (350) said low-resolution video stream by substituting (351) portions of said low-resolution video stream that are similar to one or more of said first low- resolution counterparts with first high-resolution patches obtained from said first data storage in accordance with said indexing; wherein said low-resolution video stream and said at least one high-resolution video stream are substantially synchronized video streams.
