EFFICIENT FLICKER SUPPRESSION FOR SINGLE IMAGE SUPER-RESOLUTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17820203 titled 'EFFICIENT FLICKER SUPPRESSION FOR SINGLE IMAGE SUPER-RESOLUTION
Simplified Explanation
The patent application describes a method for improving the quality of low-resolution videos by generating high-resolution frames and correcting errors caused by motion compensation. The method also restores lost details and suppresses flickers in the high-resolution frames.
- The method receives a video with low-resolution frames and corresponding high-resolution frames.
- It generates a motion-compensated previous high-resolution frame based on the current low-resolution frame and a motion-compensated previous residual frame.
- If there is a mismatch between the previous high-resolution frame and the current high-resolution frame, the method corrects errors in the current high-resolution frame caused by motion compensation.
- The method restores lost details in the current high-resolution frame that occurred during the error correction process.
- It also suppresses flickers in the current high-resolution frame on the frequency domain.
- The resulting flicker-suppressed current high-resolution frame can be displayed on a screen.
Potential Applications
- Enhancing the quality of low-resolution videos for various applications such as video streaming, video conferencing, and surveillance systems.
- Improving the visual experience of viewers by providing sharper and more detailed high-resolution frames.
Problems Solved
- Low-resolution videos often suffer from blurriness and lack of detail, which can negatively impact the viewing experience.
- Motion compensation techniques used in video processing can introduce errors and artifacts in high-resolution frames.
- Flickering can occur in high-resolution frames, especially in areas with rapid motion, which can be distracting for viewers.
Benefits
- The method improves the quality of low-resolution videos by generating high-resolution frames and correcting errors caused by motion compensation.
- It restores lost details in the high-resolution frames, resulting in sharper and more detailed images.
- The method also suppresses flickers in the high-resolution frames, providing a smoother and more visually pleasing viewing experience.
Original Abstract Submitted
One embodiment provides a method comprising receiving an input video comprising low-resolution (LR) frames and corresponding super-resolution (SR) frames, and generating a motion-compensated previous SR frame based on a current LR frame of the video and a motion-compensated previous residual frame of the video. The previous SR frame aligns with a current SR frame corresponding to the current LR frame. The method further comprises, in response to determining there is a mismatch between the previous SR frame and the current SR frame, correcting in the current SR frame errors that result from motion compensation based on the motion-compensated previous SR frame. The method further comprises restoring details to the current SR frame that were lost as a result of the correcting, and suppressing flickers of the current SR frame on the frequency domain, resulting in a flicker-suppressed current SR frame for presentation on a display.
