Video Enhancement via Related Image Patch Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-resolution videos often lack sufficient information to perform desired enhancements, such as increasing resolution, due to insufficient pixel data.
Innovation Solution
The method involves using related images with similar scenes but higher resolution to enhance video quality through patch matching techniques, identifying regions of interest, and applying these to perform enhancements like denoising, super-resolution, and interpolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video resolution is increased using only original video data, then resolution is improved, but the enhancement quality deteriorates due to insufficient information
Solution Approach 1:
The patent combines multiple related images (photographs, videos from different cameras or angles) to enhance the target video. By merging information from these multiple sources, the system obtains sufficient pixel data to perform high-quality resolution enhancement and other video improvements that would be impossible using only the original low-resolution video data.
Solution Approach 2:
The patent uses related images as intermediary materials to transfer useful information to the target video. These related images serve as mediators that contain additional scene information, which is then integrated into the video enhancement process through various processing techniques to produce the final enhanced video output.
2Manufacturing precision
If related images are used to enhance video, then video quality is improved, but processing complexity increases
Solution Approach 1:
The patent segments the video enhancement process into distinct operational modules: selecting related images based on temporal or spatial criteria, extracting useful information from these images, applying enhancement operations (denoising, super-resolution, interpolation), and combining results. This segmentation allows the complex enhancement task to be managed through systematic, modular processing steps.

AI summary
A method and systems of enhancing a video using a related image are provided. One or more patches are identified in the video, with each patch identifying a region that is present in one of the frames of the video that can be mapped to a similar region in at least one other frame of the video. For each identified patch in the video, a best matching patch in the related image is found. The video is enhanced using the best matching patch in the related image for each identified patch in the video.
