Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing methods fail to effectively address image dithering in videos with greatly changed adjacent frames, leading to reduced image quality and clarity, which negatively impacts user experience.
Innovation Solution
Implementing an anti-aliasing operator in the image processing model that includes an anti-aliasing up-sampling operator, anti-aliasing nonlinear operator, and anti-aliasing down-sampling operator to process video frames, ensuring the quality and clarity of the output video without dithering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a video processing model is used to process video frames, then the video can be processed to achieve style transfer or enhancement, but when adjacent frames are greatly changed (e.g., image displacement or rotation), the processed video frames show great changes causing visual dithering
Solution Approach 1:
The patent applies preliminary action by performing anti-aliasing processing on the current video frame before feeding it into the video processing model. This preliminary step prepares the input frame by smoothing potential discontinuities and reducing aliasing artifacts that could cause dithering in the output, thereby ensuring stable visual composition throughout the video processing pipeline.
2Productivity
If existing video processing methods are used, then video processing can be performed, but image quality and clarity are reduced due to dithering
Solution Approach 1:
The patent performs anti-aliasing processing as a preliminary step before video processing to prevent dithering from occurring in the first place. This approach maintains image quality and clarity while preserving processing throughput, as the anti-aliasing operation is performed once per frame before the main processing pipeline.
Solution Approach 2:
The patent introduces anti-aliasing processing as an intermediary step between the input video frame and the video processing model. This intermediary operation acts as a mediator that smooths the input frame to prevent dithering artifacts from being generated during the main processing, thereby ensuring high output quality without compromising processing efficiency.
3Speed
If video frames are processed without anti-aliasing operators, then processing speed is maintained, but dithering occurs in the output video
Solution Approach 1:
The patent applies anti-aliasing processing as a preliminary step before the main video processing pipeline. This preliminary action prevents dithering from being generated during processing while maintaining processing speed, as the anti-aliasing operation is performed once per frame and does not significantly increase the overall processing time.
Solution Approach 2:
The patent introduces anti-aliasing operators as an intermediary processing stage that prevents dithering without becoming a performance bottleneck. The anti-aliasing step acts as a mediator that smoothly transitions the input frame into the processing pipeline, ensuring high-quality output while maintaining acceptable processing speeds through efficient operator design.
