VIDEO SIGNAL PROCESSING METHOD AND DEVICE USING INTRA PREDICTION FILTERING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18146642 titled 'VIDEO SIGNAL PROCESSING METHOD AND DEVICE USING INTRA PREDICTION FILTERING
Simplified Explanation
The video signal processing method described in this patent application involves several steps to enhance video quality.
- The method starts by determining the intra prediction mode of a current block in the video.
- It then constructs a reference sample around the current block.
- Next, a prediction sample of the current block is generated using the reference sample and the intra prediction mode.
- Finally, the current block is restored based on the prediction sample.
Potential applications of this technology:
- Video compression and encoding: This method can be used in video compression algorithms to improve the efficiency of encoding and decoding processes.
- Video streaming: By enhancing the video quality, this method can enhance the streaming experience for viewers by reducing artifacts and improving clarity.
- Video editing and post-production: This technology can be utilized in video editing software to enhance the quality of edited videos.
Problems solved by this technology:
- Artifacts reduction: By using intra prediction and filtering techniques, this method helps reduce artifacts such as blockiness and blurring in video frames.
- Enhanced video quality: The method improves the overall quality of video by generating accurate prediction samples and restoring the current block accordingly.
Benefits of this technology:
- Improved video compression: By generating accurate prediction samples, this method can improve the efficiency of video compression algorithms, resulting in smaller file sizes without significant loss in quality.
- Enhanced video streaming experience: The reduction of artifacts and improved video quality lead to a better streaming experience for viewers.
- Higher quality video editing: Video editing software can benefit from this technology by providing better tools for editing and enhancing video quality.
Original Abstract Submitted
A video signal processing method comprises: a step for deriving an intra prediction mode of a current block; a step for constructing a reference sample around the current block; a step for generating a prediction sample of the current block by using the reference sample on the basis of the intra prediction mode; and a step for restoring the current block on the basis of the prediction sample. The step for generating the prediction sample may comprise: a step for setting a filter flag value which specifies a filter coefficient of an interpolation filter applied to the reference sample on the basis of the width and height of the current block; and a step for performing filtering on the reference sample by using the interpolation filter having the filter coefficient specified by the filter flag.
